Thank you Lisa! Thank you Rob!

Rob - by IPB, do you mean IP.Board? (that's what I found when I Googled IPB)

If so, it looks really good...and it looks like it's pretty self-contained: web hosting with IP.Board included for $10 a month. Does that mean I wouldn't need a FTP program? Also, I'm wondering what would happen if I ever wanted to leave them for another host - would my data be portable, and would it be difficult to transfer?

I played around with phpbb.com for a couple of days and liked it, but I didn't want a free forum (I want my own domain name) and I was concerned because most of the instructions and forum dicussions appeared to be written by people for whom English was a second language. I thought vBulletin was my only other option (I'm vaguely familiar with it from my occasional visits to MrExcel.com).

You guys are great - thank you so much for your help!
