Just a short note to say that I've had to take the forums on www.openvehicles.com offline. A few reasons:

Most of the questions there were support questions, and the questions weren't getting answered.
The forums were almost never used - just one or two posts a week.
The forum module itself has very few features and no notification capability.
Too many spammers signing up for accounts so that they can write forums posts about how much their sister is earning per hour.

Bottom line is that it was just wasting too much time, and that is time better spent on the project itself.

I've kept the old content for the moment - just disabled it for everyone except administrators.
