Perhaps explaining what you would like to see in a new private messaging system would be helpful. While some improvements could be made(such as a "save draft" option or a "send on [insert date and time] " option), there are also things that could be done to make it worse.
I personally like the idea; it would take care of the "fails!" even they're fun along with making it much faster to send pms. I for one know that people tend to pm a great deal of help in magick or entire conversations through pms; frankly, the window idea promises it to be slightly faster and easier.
But technically that would be a heck of a job..
Pm chat windows would need a complete change in the base level of the chatter codes that we use..I mean if ure going to pm 10 ppl,10 new windows? That would be a much greater change..
But as a regular chatter,i too hate the "fails" and would love ways that can solve the problem
Oh ok, I just thought it could be useful for example if you want to send a message saying that you won't be online for a while to all of your friends at once instead of having to go to each of their profiles and send the same message to each of them individualy. :-)
