I'd prefer a system in place where only those hand-selected are able to post tickets. If they were to allow everyone to do it, the amount of bogus reports would far outweigh the genuine ones. Only those who can recognize when it's a case of human error and when it's a case of an actual problem within the script should be able to post tickets. The premium system partly solves this problem, but not completely; there are still bogus reports being submitted by premium members who cannot tell the difference see more between a bug and their server's lack of mod_rewrite. With that in mind, a separate group of members seems like the best way to go.
