Doh, of course my idea was too simple (and I was stupid enough to try - it worked, but defies the purpose - simply lists the previous post's username).
Darren, you are right! That would be the easiest way, it would mean to add to the table, though... but other than that, this would be the way to go! The only real catch is that this would only work for future posts, not for existing ones, but some upgrades in features will bring that I guess.
Either way, we just need to store the $ResUsername in an extra field in w3t_messages (?) when someone makes a post and pull that when we display the messages. Shouldn't be so hard to implement!
