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.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hi @Sharky Kesa - that is the intended behavior for now. We may change it in the future, but we wanted to start by implementing @mentions only for comments.
Yup, you're correct. And we can't tag even when posting problems, and that's why I think they've not allowed it. Wouldn't it loo quite awkward if everybody tags their (I know 'their' is wrong English since everyone is singular, but I was confused with him & her, so I chose their instead) problems and notes with all people so that it can get a greater amount of viewers, and consequently, a faster rating. So, in my opinion, we shouldn't be able to tag in notes and problems, simply to maintain the decorum of the site. Wouldn't you get annoyed if everybody tags their questions with your name, just to get it rated faster? @Sharky Kesa
By the way, 'everybody tags their...' is a perfectly grammatical sentence [although your English teacher may disagree] and has been used in English for a long time. It's also a good way to avoid awkward phrases like 'his or her' etc.
@Nikhil Pandya@Mursalin Habib Yeah, there are some issues with when you need to type more than a first name to find the person you are looking for.
The way to get around this is to actually omit the space and type straight through from first to last name, unfortunately for Nikhil, you have to type all the way to @nikhilpandy before he is the only person in the list. However, due to context aware searching, if you follow Nikhil or Nikhil is associated with the thing you're commenting on (posted the post or wrote a comment) he should show up towards the top.

On a related note, it is not possible to tag certain people. Try tagging Nikhil Pandya.
