A bit hard to explain... when we reply to something (without using the quick-reply), we have a new text box. It's white instead of pale green (not a problem, just specifying

), and sometimes, when you post, spaces can become double spaces. I mean, spaces like these:
A
B
(will become)
A
B
Happened to me a few times. Then, there's a bug with smileys switching places with the space that precedes them, but I think that only happened to me once. (ETA: It just happened again while editing this. >_<) I dunno, it IS very hard to explain, but I tried.
