Can I post links to covers that I like that others have performed and praise them or is that not allowed?
If you want to geek out about utaite/youtaite that is fine, and you can do that under Utaite Talk.
Just be sure not to spam, i.e. don't post post with one cover, and immediately after another post again containing only one cover. Instead you can post a post with multiple covers, and praise them :)
What do you think?
