Though I admit having had an "Aww my eyes" moment too just now. ;-)
Maybe besides having a darker background, have it also a bit more "vague", if that makes sense? I mean, so that you're slightly more forced to look at the text rather than at the background. (A bit like this textbox thingie, I guess)
(and this is where I start nagging. Sorry. Here, have a hug. *hugs*)
The box of the current message could be a bit bigger, though.
Also, I don't really like the IP thingie being so out in the open. I dunno. I guess I'd prefer to have that not on there. Or maybe only for the person that goes with that name/addie and you and/or whoever the admin/mod/editor is.
I guess the same goes for the text about the browsers on top of the index. As far as I remember, you've included the browsers that maybe 99% of the people have/use. The other percent or less will just have to stay sane. :-P
Meh, if you want, I could try and make a design? If it stinks, no worries, just don't use it. If it works and you'd like to use it (or part of it), then that's cool too.
P.S. Thank goodness those tiggers of yours got their own bit of sevspace! Maybe that gives the catafobic Sevilians amongst us a bit less stress here! ;-)
