well, mengs suggestion is a good idea for atleast in that way mods can watch member without being watched or spammed on their pms as well as it can be a bonus function for non-mod contibutors and i hope in this way other members will try to think if what they can contribute for the good of everyone not just foe themselves. in this way also they will feel that theyr contribution to the forum is being recognized. in short a simple way of appreciating contributors.

my best example of a very helpful member is sir bobcbar who deserve those special functions
