ok, this may have been posted before(I did search the forums, for this topic).Anyway back to the subject, well how about, a messaging system which didn't require you to click refresh to get the pop up, this would save time and would make things easy, in terms of invatation and private messages.

If you're not clicking refresh, that means the site then has to bombard and probe you instead. Battles used ot do it, it was a nightmare of lost messages being typed
And then there's the swallowed bandwidth...

yes, i know, I had thought of that, pehaps a little java console would be better..
