How about mods having to meet some minimum standards....

[cheat-master30]

I personally disagree with the idea of mods having to meet some minimum standards due to the fact that even if these standards only are based on the coding and instructions given at first, nearly every site I've seen which has added a set of rules for submission has then basically used it to remove or ban content the moderators don't personally like, and with all due respects, I don't want to see moderators playing judge, jury and executioner with modifications like I've seen on a couple of other sites in other subject areas, especially with some of the more controversial submissions (aka, anything seen by some to be controversial or quick activity/content boosting would probably get banned if it went that far). The other reason is that only some mods need these instructions, things like BB code, or minor edits, or just product/plugin files really don't need a step by step list of instructions how to install or uninstall.
