Nah, forums are open discussions, if it says 'solved' people may skip past it, however they may also know a much simpler solution...or if they people who 'solved' it just lead them to some resources, another person may know better ones, or possibly the solution themselves.It kinda restricts things, I know its not forcing them to not post (which would happen if you closed it) but it still can invariably skip over other solutions.
