From my dealings with demerphq, diotalevi, bart, and castaway, I know that they would appreciate a /msg at least as much as, if not a lot more than a simple ++ or two. Sometimes a kind word of thank-you goes a lot farther than yet another positive vote to someone already solidly ensconsed in the halls of sainthood. :) I think I can go out on a limb and say those four contribute for the pleasure of being helpful, and that being the case, a simple thank-you is the best kind of reward.
