I have some tasks piled up that require work with a partner. I need to be tackled, disarm someone with a 2Hw, be tackled, and to be taught war cries. I'm a beginner in all (1-2 ranks).
There are a bunch of informational commands (who, service, profile, gld) that can be used to track down potential partners in game, but the key is probably being in the Landing on the evening when double points are on offer. I haven't seen anyone doing reps or heard anyone asking for a partner during the daytime since that was introduced.
