I'm considering buying and using gforum along with my lsql install. here's a couple of questions that I hope someone can answer:
1. I currently use vbulletin. I've read that I can't import directly from it, so I'm planning on going vbulletin-->phpbb-->gforum. is that sound? a better way?
2. currently I have lsql on mysite.com and my forums on forums.mysite.com. I'd like to keep it setup this way, if I do will there be any issues? (what I want is to share userbase, etc.). Ideas?

thanks in advance!
Will
