I am new to developing web sites and I was wanting to know if having your blog title relevant to your content really that important?
I see your title, "How to determine Topic ID " does seem to be spot on with what your website is about however, I prefer to keep my title less content descriptive and based more around site branding. Would you think this is a good idea or bad idea? Any help would be greatly valued.

It's just one topic amongst thousands posted here.

I suppose, it would be most relevant way of presenting things, if each topic would have 'miniBB' word some way attached to it.

It would give an impression that thousands of topics all are related to miniBB.

But those topics are posted by regular users, they just don't simply care about miniBB's relevance, they need a support. So they get it properly and in time. That's the basic deal with a miniBB-based forum.

As about the blog you post on your own, let's say if it's related to "money", then each article you create, may merely contain "money" in it's title and that may help you to rank higher in the crowd of millions of other bloggers doing the same.
