I've recently setup my official vBulletin 4 demo site over at
http://mysticdigital.com/demo/vb/
If you are a vBulletin 4 user, clan member or leader, and would like help working on your site, I'm there to offer any advice possible. Feel free to stop by and ask anything from setup, mods, content management, tips & tricks - I'll do my best to help any of your questions, whether you're a novice or full site owner.
I'm also preparing a wave of free tools & Knowledge Base for site owners to start up or improve their clan sites more easily. With 5 years of development experience, I'm looking forward to giving back to the community wherever possible!
