In my experience on other forums, if you have a sub forum where anything goes, it just bleeds over. People get in arguments and chase each other around to other parts of the forum.
No, it will not be a thing on Rokslide. We try our best to keep this place positive and informative, and an anything-goes subforum would do the opposite.
The general forum runs the gambit from what tires for my truck to I want to move to Argentina to retirement investment advice. I can't fathom what you are looking for beyond that. The hardest thing to give someone is something they already have and won't recognize.
