The big grin smiley looks kinda creepy to me
The "classic" smilies are still there, you just have to click over to the second page. I have no idea how you might get them with just keyboard strings like the old colon-dash-close parenthesis. 
Re the typing box spell-checking, y'all just made me pay attention. The site was broken for Opera a while ago, and now I realize that several months ago I was used to seeing spell-check in Firefox text boxes like this, but they seem to be gone now. Was the change to FF or are the Stardock forums somehow ducking that functionality with the latest edit boxes?
Re spelling in general, Phoig, it is *always* much harder to check your own stuff. Your stupid brain does "corrections" that never make it to your fingers, so your only hope is getting a draft done early enough to put it down for a good while before you proof it. I went to a writing-intensive college where we actually had a *math* professor who put his manuscripts in a drawer for a *year* before he edited them.
