One of the thousand things that annoyed me with vBulletin is all the vB forums that people create just to earn money from the name. I know it ends up good for vB in a way as it is free advertising, but it gets confusing and damn annoying seeing all the sites for vB. People new to the software could also, im my opinion, get misled thinking they are on a genuine site, etc. Are you going to limit people using your brand for their own gain? A mod site could be a good idea, or perhaps a mod section add-on to this site, operated by you of course. I'm seeing sites appearing already for your software, and it really is silly. If you want xenForo information, come here, simple!
