Good afternoon, I'd like to know where we can register our community (do not I mean calling at league for now)?

I don't understand your question.

there are communities registered with LFS (https://www.lfs.net/links) would like to register a community there

Okay I don't know but maybe mail devs

Think some links are dead

I guess, you have to post it here, if it's a website. https://www.lfs.net/forum/thread/72-LFS-Websites
