GenuinelyI think that there is a great post grad thesis available here. Depending on the profile of users, popularity of forum and thread titles what is the maximum number of useful posts it is likely to have. Create a Forum formula that calculates exactly how many posts can be added to a thread before it goes off topic.
If we had it we could limit contributions, that would then make for a great searchable resource.
As it stands. 1k+ posts make it worthless to read through
Selling something? 10 posts only
Wanting a fix for something broken? 20 posts
Photo albums 50 posts?
General chatter 100 posts
Brexit - 0 posts before someone gets all militant, usually me.
