I've seen some other people do this, so why not, I'll jump on the bandwagon.
First a few things: I am a 8th grader who is taking Geometry in class, but is working on advanced Pre-calculus concepts and a little Calculus for fun.
You can ask me on advice, whether it be doing math competitions or how to write good problems. Any question is encouraged, as long as I deem it fit for me to answer (no privacy-infringing questions please). Or you can just talk about whatever you want to talk about with me :3
So go ahead and ask!
