I'm a vBulletin fan to be honest, just used it for so long, the Admin support forums were great for everything too.
The Honda forums were pretty good to be fair, high traffic, lots of different topics a very good community with loads of events and awesome sponsors.
Then people get older, circumstances change, the cars age become cheaper, scene, fashions and opinions also change.
That said, what I might now find a annoying, same question, cliquey forum is fresh new adventure for someone else to get into with nothing to loose.
Just never take it too seriously, help where you can and don't get MAD, it's the internet.
