Well this is going slightly off-topic, but I've used forums with more subforums and those suck to. I already have to check 4 or 5 different forums I'm interested in reading - I'd rather not have to check 15 of them. Plus there's already overlap. Say I want to ask about a good commuter light - will I get better responses in the "Lighting" section or the "Commuting" section? (Truth is, the Commuting forum just has more readers so I'd probably get a better response there).

What I'd really like to see is to go to the forum and create a page that lists out all the new threads in the subforums I choose, so like road, mountain, commuting, lighting, but not advocacy, folding bikes, etc.

Sorry...I guess I've gone totally off-topic eh? I'd respond to the OP's question, but I don't know how much £10-£30 translates into in US dollars.
