Question

Can anyone tell me why my avatar is small in some posts and big in others? I'm very confused and would like to know how to fix it.

The size of your avatar is dependent on the amount of lines that your post contains. You can't really 'fix' it. But you could do less 2-3 lined posts and more 6-7 lined posts.

I believe you were looking for this thread:
Avatar/signature thing?

There are a number of levels:
Very short post (few words)= No avatar/sig
Short post (1/2 liners) = Small avatar (50x50)
Medium post ( 3/4 lines) = Normal avatar (100x100)
Long post (4 lines +) = Normal avatar + signature

NOTE: These levels may not apply to mods.
