( and I am not sure if it still carries that much weight with google anyway. )
what to do? I don't know. I would suggest either not worrying about having one at all, or be prepared to update it on a regular basis depending on how often your board gets new posts etc.
you do know that the sitemap is regenerated all the time, depending on the cache setting?
Not sure where did you get your strange idea / misinformation about sitemaps, but all of them what I know of also refresh. Otherwise no site would use them and google would not recommend them.
