How long will it take to get indexed?

I know you cannot fully answer this question, as know one can really.

I guess my forum would be a good test run for vBSEO. Reason being is because I started a brand new web community using vBSEO right from the getgo. I had about 30 posts when it was installed, maybe less.

Anyways, MSN seems to be loving it right now... with about 500 pages indexed. Though Google is still poking around. I get quite a few hits from it daily. I am using the Yahoo/Google Sitemaps generator tool which it submits to google on a nightly basis.

I was just wondering how long I should expect to wait before my site starts to become indexed by Google. I have two pages currently sitting in Google's index which really have no relevancy to the forum at all (The main page, and a sub-forum for posting musical tastes - my board is primarily a web community)

I was just wondering exactly how long the process might take. The forum is about 2 weeks old using vBSEO.

So, I don't know. Any feedback as what to expect or why it might be taking so long?
