Good points, RL. Especially this one:
"With the approach of making it based on time, you are rewarding someone for sticking around and being loyal to the board. That would reward people who "lurk" on the board, but rarely post. I think too often those people are ignored. The argument to that, though, is that they will continue to lurk. Under the rules now, I believe they can read all forums and threads, just not post, which is fine for them, if they are just going to continue to lurk."
I agree that it's pretty easy to accumulate 200 points if you post a lot. Perhaps the solution would be to raise the requirements to 6 months and 500 points.
