Oh, no, definitely
include your signature with a link to your site. Even if it doesn't give you any SEO benefit, if you're a valuable contributor to the forum and appear knowledgeable, the real people on the forum may click the link to check you out. I know lots of people who generate a good bit of business through forum signature links by providing useful information and being a valuable member of the forum community.
@Tsid: according to the folks at Google, no, you will not get a ranking boost from a nofollow link. That's the whole point of nofollow.
