What is the time commitment?
 

The company I work for is looking at creating a user community for our products. I know this is all relative, but what type of time commitment do you think we'd be looking at to simply manage the vBulletin community?

I have no idea how many users we're talking about - can anyone give me rough estimates based on the number of users they have or the amount of monthly traffic? For example, "I get 20,000 unique visitors per month and it requires one person to spend 4 hours per day managing it". or something like that...

I am not looking for ideas on how long it will take to set the community up - just to manage it. We're planning on using the blog and forum.

For a community of 1000 users? 10,000 users?

Any help from your own experiences would be much appreciated!
