Basically, a communitylocke is where participants Nuzlocke a game from the same set of games (A FR/LG communitylocke, for example, or a D/P/Pt communitylocke) all following the same rules. The players are then awarded points based on events in game, such as positive points for catching Pokemon or beating important trainers or negative points for losing a Pokemon. This then adds a competitive aspect to it. There are checkpoints, in which every trainer has a couple of weeks or a week to get to the next checkpoint.

I'd love to propose a B/W communitylocke, if people are interested? I can set up the rules and such.
