When accessing the site from my Android, I ran into text getting cut off... only by a few letters, but I have to turn the screen sideways to read it all. I just took a quick screencap of a recent convo so you could see what I was talking about. Simple mobile detection but still.
And kinda unrelated, but another potential mobile shoutbox issue. Selecting an orange user (tried AllyJoy and Jester) from the shoutbox either does nothing, or else sends me to a blank page, with no errors thrown. Acted like I clicked a dead link. But only from mobile could I replicate the issue. Selecting members, admins, or VIPs, worked just fine. Maybe you were playing with profile links earlier?
And one more! When clicking 'preview' of this post, it also threw me to a blank page and I needed to reload the page to recover my post. I had that happen a few days ago when I was sending a PM as well (I'm compulsive and have to preview everything before I post it!).
