These Google Ads are more or less the only revenue. Even if these decreased a little lately, they still cover the server cost.
There are also from time to time other ads too, on some specific pages.
The forum is a separate site, not handled by me.

Just curious, how does this site support itself? All I see on the main site (non-forum pages) is one small text-only ad on the top right. Surely that one ad is not paying for all the storage and bandwidth costs each month?
