Search for active communities

I'm in search of active communities to discuss CP problems and solutions, especially old problems of which there are no proper editorials(no code, no explanation, broken hyperlinks, etc).

I tried searching discord, Reddit, WhatsApp Groups, but none were active. So your help is highly appreciated!

I usually need to discuss div2 C, D problems.

currently, I'm solving A2oj ladder div2 C

I would also like to help beginners to solve A and B problems.

Thank You in Advance
