I looked into this, and saw that there were a few older topics that went over it, but that few actual suggestions were forthcoming. I am posting this new thread because I actually have some suggestions that I think would work. Because: A) There are now over 500,000 registered players, so the chances of almost any game not being desired by at least 1,000 players(the criteria I saw used in an earlier, closed thread) is extremely slim, and B) The number of games out there is staggering, and continues to grow every day, I suggest that you should -- Allow everyone to set their own tags. New tags would either go through pre-moderation to ensure that they conform with the rules before being added to the master list, or they could be added to the master list automatically and then subject to post-moderation, which would be done via a flagging system much like used for forum posts. I can see benefits to both approaches, though I'd probably go with the latter myself. Either way, a flagging system should still be in place since moderators are human, too, and an errant tag is likely to get through occasionally even if using pre-moderation. However, there should be rules. I don't know all of the rules that should be in place, but to keep the list both useful and from getting out of hand -- it will already get large enough without there being 50 different tags referring to the exact same edition of a game -- I would suggest at least the following. 1) No abbreviations. If the game has a full name, use it, even if that is not what it's called in common parlance. (Ex: GURPS - Generic Universal Role Playing System) 2) Letters and Numbers Only. Most punctuation marks and other special symbols should be omitted entirely. Ampersands should be spelled out. 3) Include the subtitle if the game has one. 4) Specify any edition other than the first. (Ex: Vampire the Requiem Second Edition, Dungeons and Dragons Fourth Edition) 5) No any/all tags. Each tag refers to a specific game, or to a specific edition of a game when there are multiple editions. If you want multiple editions of a game on your list, add each one separately. 6) No crude or vulgar tags. In addition to the rules, a tag suggestion feature -- such as the one used on tumblr -- would be useful. At first, while people are adding many new games that aren't already on the tag list, it wouldn't be nearly as useful. But over time, as the list grew, it could save a little time for the people filling out their profiles and a lot of time for the moderators who have to clean up behind rule-breaking tags. As long as the rules(whatever they ultimately end up being) are enforced, this should allow players to tag themselves for any game that they want even if a tag for the game they like doesn't already exist while keeping each tag, no matter how large the list ultimately gets, distinct and truly useful.
