I've belonged to two different car forums before and both were shut down after a year. Why? Always a money problem. There were a lot of members on both sites, but the admin couldn't afford to keep it going. The admin even got so desperate to the point that he was begging for donations to keep the forums going. How sad...
But this forum seems to be up and running fine. For three years even!!! So let's see if we'll see Computerforums around in the next 3 years. Hopefully with some more modifications and new look as we go.
