I think the forum should invest in the following companies:
Pop Secret. They are a popcorn manufacturer whose profits will rise when users buy their product while enjoying the drama that takes place on this forum. If people had a forum owned brand of popcorn to buy then the overall browsing experience will increase.
Bristol-Myers Squibb. They are the maker of prolixin. Their profits will increase when users take this drug after incurring a little bit too much stress. The many crazy people on the forum need a safe way to prevent them from hurting themselves or from hurting others.
If the forum does not wish to invest in either of these companies, then they should get a referral link so users can buy their products while benefiting the forums.
Either of these solutions should produce more then enough revenue to get rid of the annoying advertisements contained in every thread.
forget "New forum Software".
I'm hearing about it from three years ago!
