I sent him a message about the problem, hopefully Mr. Karlith will fix it himself.

You may want to change your image host, as you cause a 'certificate failed' error to come up if anyone views your profile or receives mail from you. I suggest hosting your avatar image on Imageshack:
this is the error we receive when looking at your profile or attempting to load your avatar picture:
There was another person with an avatar that caused this. Since I am not getting the error message anymore, I guess that since 3 weeks passed, it was avatar-related.
I don't remember who that person was though.
But now that I know the source to this problem (or at least one source, the other seems to be a banner as others here have pointed out), so when it appears again I simply report it to the ASims after the character with the avatar doesn't change it?
