Have a ask a question forum.. A user can post a question about anything, such as a problem with something or a question he cannot find out about.. Other users will respond to them.. The user who answers the question correctly (accepted ans) will receive a donation from the user who posted the question.. Afterwhich, the thread can b locked by a moderator and marked "[Resolved]"..
Every forum is like this - users can ask questions in appropriate forums, eg. Computer Problems and Support. If there was a general "questions" forum, the moderators would have to be online 24 hours a day moving topics to the appropriate forums.
If you need to ask a question, search the forums first. If the question hasn't been raised before, open a new topic in the appropriate forum. If a user answers your question and helps you, then you may donate FRIH$ to them if you like, but this is up to you.
