A lot of forums do this, they just piggy back on the newsgroups - makes
their forums look busier, and they get to display their ads alongside the
content.
*Sigh*, one of these days I'm going to start write to them asking for a
share of their ad moneys.
There's like 10 different "web forums" that carry Microsoft Public
newsgroups, it's annoying too because the username doesn't translate
correctly into the forums either.
