Keyword on ALL of my forum topic titles

is this bad?

[chopin2256]

I have an invision board, and putting in a name of the site in a control panel will produce that title in EVERY single topic page that google will spider. The format is this:

(*Sitename *Keyphrase -> Topic titles)

The *sitename and *keyphrase are repeated on every title page. So far, I have about 10,000 or so topics spidered. I was just wondering if this is a bad thing for me to do? Having the name of the site, plus one keyword on every topic page? So far so good, I am doing pretty good in the SERPS, but I never thought about this until now. Should I delete my sitename and keyphrase from being displayed on every single topic page? Or does it really matter? The generic keyphrase is relevant to all my pages, but I dont want to be dumped AGAIN from Google. Opinions?

If it's a logical location for the phrase, as "webmaster" might be here, for example, I'd tend to leave well enough alone. At least from what you describe, it doesn't sound too dodgy to me, and one repetition certainly won't constitute stuffing.
