Editing posts and something else

Hello!

The problem is that the service does not allow me to edit my posts. I’ve tried several times. It asks me for a Username and Password. I enter them and nothing happens. Moreover it says that i’m logged in at the moment.



Also, is there any way to upload animated avatars? I feel myself better when seeing moving images. It’s not critical, just a question. :smiley:



Thank you very much!
