Relevancy is not important as of today. Down the road maybe, but I could show you some sites in highly competitive niches that have backlinks from many unrelated sites. These sites are ranking top ten for 50 million + pages.
But it is better to be cautious and get links from sites that can potentially send you traffic. Outside of that, you have free web/article directories, social bookmarks, free press releases, blog comments, classified ads, etc. There's lots of ways to get backlinks for free.
And you are safe to use your site in you forum signature, even if the site is unrelated.
