How do I go about talking to someone in the forum on a IM type of thing.

You cam Private message someone by using the PM button in their post, like the on right above these words. :cool:

But thats more like an email, without having to remember a whole address. Real time MSN style chat is coming apparently, but its not here yet. (In case you havent noticed were overloading the current server as it is). But for now if its really important arrange to use MSN or similar. But unless its private, why bother? Forums are fast enough.
