How about a TA Move of the Week.

A selected member posts a move that members must try to replicate in multiplayer aikido during that week. This move can come from the technique library or something of their own. Obviously the move needs to be something that can be replicated.

At the end of that week we vote on who's replay demonstrate that move the best or just the replay that is most like whatever. The winner will then decide and post next week's Move of the Week.

This will NOT replace Tiers but it's something to involve the org and keep steady activity.
