Amazing - I found the answer relating to the disappearing WYSIWYG editor! I had set the Mobile styles to be the same as the "normal" style. WTF? Setting Mobile Style to Nothing cured it. That's what was driving me crazy earlier. I found this on the vBulletin site after some serious searching. I think things are settling down. I'll work on a bnanner image for TwistedBlue now, and I think I'll buy a light theme to go along with vBulletin Default.
