First of all, I'd like to say that I think it is great that you are trying to improve the submission system to be the best as can be. However, you've made some decisions for which I'd like a motivation:
- Two weeks ago, voting started after three days. Last week, voting was possible right from the beginning, but the votes were hidden. I had my doubts about this because it partly brought back the timezone problem, as early solutions were more likely to get the most votes. It seemed to work pretty well though. But this week, the vote count is again visible right from the start. The only thing different from a few weeks ago is the fact that they're shown in random order. This brings back the timezone issues people have been complaining about, so I'd like to know why you chose to use this, as opposed to what you had.
- From this week on, we can only submit one problem per problem set. Why? I'd like to submit multiple solutions per problem set to practice my proof-writing, and if I can't make my solutions visible, I'm not very motivated to write them in the first place. Also, I don't think you've put it very clear, as it says "You may publish one solution per week.", which wasn't clear to me. Per problem? Per set? In total? I just assumed it was per problem. After that, I put a lot of effort in another solution, and only after I'd written it, it said that I can't publish it, because I had already written one this week.
Also, I've seen quite some questions about this system from other users, without an answer by the staff:
- Why can't we edit our solutions? I see it a lot that the solution writer finds a mistake in his own work and just puts it in a comment, while it would be much neater if he could edit his original solution. Of course, copying other solutions shouldn't be encouraged, but what you could do about this, is only allowing a certain amount of characters that's edited, or the possibility to submit an edit request rather than edit it right away, so a staff member can decide whether the edit may be put into effect or not.
- Do we get points for correct solutions? I remember that somewhere it said you can get up to 1000 points for a correct solution, and you can be deducted 50 points for a wrong solution, but that's the last time I heard of it. When I go back in the past problems tab to the first week of the renewed system, I see that you haven't chosen featured solutions (which is good I suppose, as people get to see multiple ways of solving a problem) and I have no idea whether I got points for my solutions or not.
- A few weeks ago, after you submit the right answer, it showed the key techniques for that problem, but that's gone now. Will it come back? If it will, then it would be cool if you can spend points in order to see those techniques for a problem that you haven't solved yet, in order to figure out how you can approach it best.
- As I pointed out a while back, there seemed to be a limit on the number of solutions that could be submitted per problem, and last week, it was still there. Now that we can only submit one solution per problem set, it's not very likely that a problem will get over 50 solutions, but the limit shouldn't be there.
Here are some other issues I encountered with the new system:
- Sometimes I try to upvote a comment, but it doesn't do anything. Other times, it does work. It's pretty strange.
- The solution box is way too small to begin with. I know I can enlargen it, but after I preview my solution and go back to editing, the box is small again. This is pretty annoying. This also applies to the box I'm typing in right now, it doesn't remember its size.
To conclude, some feature requests:
- The most requested feature probably is the ability to discuss a problem rather than submit and discuss a solution. Although being able to submit solutions and discuss those with others is fantastic, discussing the problem itself might be even cooler.
- Before I submit an answer to a problem, it says "Show solutions", but after I submit the right answer, it doesn't say how many solutions have been submitted, while I'd like to use this number as an indicator of whether it's worth it to publish mine. I'd like to suggest a box on the right similar to the Solved by users box, but then for who submitted solutions, and more importantly perhaps, how many solutions have been submitted.
- It would be handy if the checkmark in the green circle would be filled with some color if I wrote a solution for that particular problem, to make it easy to see for which I haven't done so yet, and to easily check how my solutions are doing, whether they have comments/notes, etc.
That's it for now. I'm sure you have good reasons for the choices you've made, but please, communicate more often with your userbase.
