Not sure how this software works, but with http://www.dcscripts.com/
these guys a member can be put on probation. That means their posts do not go through untill approved by a mod.
It works as a way of cutting back on squirrely posts.
There is the problem for boards such as this that specialize. People that might be perfectly agreeable on firearms could be pretty nasty on political issues.
The idea of limiting the number of posts per thread strikes both ways. It limits the amount of drive-by one liners, but it also hobbles people who are making a genuine contribution to the thread.
This is another place where, if the software allows, more senior members would not have the three post limit.
More mods wouldn't hurt but they won't be needed after the election.
