I'm glad XD. Writing CSS is sort of a hobby for me.
Ahh, I just noticed- the icon table gets stretched by the text. I think it can be fixed (or at least the blue frame removed). I wonder if you'd let me login to the community account to see what can be done? It's hard to edit code without seeing results, and I can't check it on a normal account. I could write by guessing, but it would put extra work on you to check and report if it worked.
I think it may also be good to add a light border or bg color for the comments, since the way they are now, it's confusing whether the separator line belongs to the top or bottom comment.
Also, I see the layout works fine for threads with 50+ comments, but dies on 130 :/. I'd guess 100 is the limit of still being readable. Looking at the GJ Elysium, the posts rarely got more than 50 comments. But if you plan long chats for the RP community, you may want to pick a simple layout with no CSS.
