If people want it, then create a new domain webmasterworldanarchy.com which looks like this one completely but the links between them are nofollowed in both directions. If it looks as if it is part of this forum, i.e. in the index, then those people will stay in droves. :^)
Frankly, the Supporters forum donation isn't a fee. I am happy to pay to keep the site running as long as I can afford it.
Ads don't worry me. An ad-free social media site is a rare exception today and I don't avoid any site on account of its ads.
There are plenty of sites where you can mention your site to discuss a problem and they create a big problem for newbies who can't tell whether the advice is good or bad.
