Can anybody here help me out by pointing me at a site where I can find forums for all kinds of topics?
Any help would be much appreciated…!
You can try http://www.pestosoft.com/ but it’s pretty useless. I’ve only heard of it because they mention my site 
Useless? USELESS?!? And after all I’ve done for you…
There are thousands and thousands of different topic areas addressed in usenet newsgroups. If you are running windows crank up the newsgroup reader included with Windows Internet Explorer and see if the topic you want information on is addressed there.
In re-reading the OP I see I’ve caught the clue train a little late for your silly little exercise in recursion. How droll for troll.
I used to be a Compuserve member and they had the best forums about every subject. Unfortunately their customer service sucked. Finally they made a mistake and billed me $4000 instead of $40. You’d think they could straighten things out but several years later they still claim I owe them the money. Needless to say I did not pay and I told them to take a long walk off a short pier. You can read their forums now as a visitor but I am not sure you can post. http://www.compuserve.com
As an example, the Sailing Forum but they have hundreds and hundreds about everything you can think of. The level is quite high, they are very moderated, they do not allow any crap from posters and the level is quite high.
I think this question will do better in our forum “In My Humble Opinion.”
Off it goes.
