Over the next two years it gained around 70 members and not very many posts (because I wasn't really focused on it) then without much warning a popular UK cycling forum I had been using merged with some other cycling forums and a number of people who didn't like the result ended up on the doorstep of CycleChat!
I welcomed them in, put the virtual kettle on, broke out the choccy biccies and then we set about building our own forum how we wanted (the kettle is much bigger now there's 20,000 of 'em and we had to get a virtual dishwsher for all the cups!! ).
The numbers continued to rise as people told their cycling friends and we soon outgrew phpBB so moved to vBulletin 3.x series then much later to IP.Board and then in late 2011 to Xenforo.
I've been very lucky to have a dedicated team of moderators helping me over the years, but for something I've build in my spare time I'm really proud of what we've achieved and continue to take pleasure in reading some of the funny things our commnity members post and seeing new friendships formed and flourish.
So ... how did you end up owning/running a forum?
