I'm involved.
When I'm looking for parts I look at the thread titles. If i don't see what I'm looking for I move on. A thread titled something vague like "Suntour parts" or "lots of tires" isn't going to get me to open the thread. Having one or two people post a bunch of stuff and monopolizing the forum typically hasn't been a problem. If needed, I'd rather we come to a consensus on the amount of threads one person may have at a time. And then I can take that info to the Forum Administrators for consideration.
