As for Yardartist's original question...
Personally, I'm not a big fan of having a Karma prerequisite for DBTC threads, but the beauty of the program is that everyone gets to make their own rules.
The bottom line is, the Karma number is just a number.
Much more important is driving the continuation of these corals being fragged. That is a big part of the reason we are making a greater effort to recognize 2nd gen and later. The point is to see frags of these corals continue to come back. Even if "come back" means going to another club.
