Hey - I saw you were online yesterday and I got the stuff you sent me, but I wasn't sure how to find you. And then my computer gave me the Blue Screen of Death (again), so I gave up for the night. Heh. I'll try to get back on it soon.
click on the button that says communicate. a window will pop up with two tabs on the bottom it, one says contacts one says local chat. Click on local chat and if someone IMs you another tab will show up on that one with their IM to you.
