Text ads are alright, don't know if they would bring in enough though.

Graphical ads altogether don't just look awful, but detract from the look of professionalism a community may have. They can be added to some website s provided they fit in well with the layout, but this is only really possible on a CMS or two-column system- not on forums.

Ads bring in revenue but at the same time may drive away potential new members, rendering them pretty much useless anyway.

Just my 0.02c.

Be nice if I had a PayPal account, then actual spare cash to put into it. Cash I could source up, the other issue is the killer.
