I used to belong to a forum about guitars. On that forum, we created a new section for people who either owned their own business or had special skills of some sort. In that way, if you were looking for, say, an expert on guitars, you could search through the directory of members here that might be able to help you. There is already a level of trust with members, and we get to help each other out if it's at all possible. Would there be any interest in doing this here? Just a thought.
