is it easy to convert VB to Drupal i have ~ 1500 Post and ~1300 Member or the best way is to integrate between them i'm building a community website www.egynote.com
It's really worth it, we're starting out with a Drupal forum because you can make a drupal forum look really nice and work like VBulletin, but it's way cheaper and updates are free and Free. If you go on Drupal.org you might be able to find more help on their forum. I just converted a blog from blogger to Drupal and it was probably the best move I've made. I was able to keep all the original posts as well which is nice. Hopefully your move goes well for you.
