Hello Frug, thanks for the answer. Also thanks for the chat program, it's worked really well for my forum.
Yes that's exactly what I'm looking for.
Losing whispers on a page refresh isn't a problem. In fact it's actually good, since it will make for an easy way to demonstrate to users that the modification is in place.
My only minor concern is the possibility for abusive messages over whisper - or alternately, bs accusations of abuse; everyone loves a good he-said she-said - but I prefer that over the risk of my / other admins' reading conversations people expected were private. I don't like the possibility of doing it inadvertently or the temptation to do it deliberately.
Is this something you'd be able to do for me / tell me how to do? I don't know what your time commitments are like, and I don't wanna assume that it's an easy thing to put in because god knows lots of things sound like they should be easy until you actually go and do them.
If so then great, if not then hopefully someone else here can help me out. If not that then there's a couple other places I can go for help, I know one or two, like, Javascript Guys I can talk to about it.
In whichever case, thanks for taking the time to look at this, and again, thanks for the great chat client.
