# testing

Some of you might have noticed a few new things about your upper left sidebar. We have made some recent changes that we hope will:

• Allow a greater diversity of problems and notes on Brilliant to find an audience.
• Provide more power to our members to arbitrate on what is good and what is not.
• Allow posts on Brilliant to self-organize and be more discoverable.

The topics in your sidebar have been changed to their corresponding tags. Instead of only being able to easily access posts that fall within our official topics, you can now save any tag to your sidebar. Whenever you tag a problem, note, or set, it appears in that tag and the page of any other tag that you designate.

Your sidebar can have whatever you want in it!

This is what my sidebar looks like:

sidebar

There are a few different ways to view a tag page. You can filter your problems by the level of your choice, and you can also choose to view by popular, or all.

popular

All displays everything within that tag, while popular only displays notes, problems and sets that have received significant likes and reshares.

You will notice that you can only get ratings in the main topics, as opposed to in all tags. The "official" tags look like this:

officialtag

While all other tags look like this:

Justforfun

Unfortunately, we will probably never let you level up in the tags #IntroduceYourself or #JustForFun. However, if Brilliant grows to host lots of problems in something like #MicroEconomics, we would consider letting ratings apply to it. In the future, we intend to make suitable tags into official tags as communities blossom around them. Currently we have #Chemistry and #Biology in the "official tags" section, but you cannot get a level in those tags yet as there is not quite enough activity in them to make having a level meaningful.

The explore section still exists where you can see the full river of everything new coming into Brilliant. Remember, liking and resharing plays a crucial role in determining what problems get solved on Brilliant. So please everyone, don't be shy about liking and resharing the things you enjoy on Brilliant. It helps the community identify what problems people similar to you should solve and helps our creators find audiences for their ideas.

Let us know what you think about the new sidebar, as you start to play with it's possibilities.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Can you please who's sets should I solve in order to level up my rating in different topics.

Woah; this site used to have a sidebar. It would be really nice to experience groups and custom tags.
