The adsense is dropped to the bottom of the forums for any/all registered users, it helps to offset the hosting, we don't have any other forms of advertising, and we're getting set to offer users their own email accounts and personal web space for no charge.. 'tis out of our own hearts that we give.
but yes, it can be bothersome. i can't really ask you guys to register to check things out, but i might suggest it.. as you'd note the adsense drops to almost nonexistance for registered members.. and.. well, yeah. =]
thanks for the comments, btw. any opinions/criticism is welcome!
