Re: "Hi, I can't figure out how to private message you, can you PM me instead, then I can just reply to you."
Of course. In the upper right-hand corner of the page here should be a link to your Private Messages. I have sent one your way, and if you look at it, you'll see at the end of it a space for you to type a reply, as well as a Submit Message button to send it.
Alternatively, you can use the following link:
http://www.polyamory.com/forum/private.php?do=newpm&u=47455
... which will basically do the same thing (but without the text of the message I'd sent to you -- which doesn't matter because there wasn't much text there to speak of).
Let me know if you hit any roadblocks or have further questions.
