Haha, yes, that's what I meant... Aaaw, I really wish english was my native language, so that I could communicate properly with the world...!
But thanks! It's working now! Only, you can't browse for an avatar? I had to insert an URL instead...
I thought a personal photo would show up as your avatar...
(Thought I tried to upload a personal photo by browsing for it, but then some kind of error occured... But I thought there was a re-sizing-function that automaticly resized the photo to the correct number of pixels... But either that function was not activated, or... there was a real error, I don't know...

)
And by the way, can I scale down my avatar in some way, even if it comes from an URL?
And thanks David! Haha, I think I looked everywhere
except in "Board Options", because I didn't really understand what that meant. Typical... But thank you! Now I get it.
