I do think we can come up with something catchier (shorter) to use eventually, but for now, if we can't come up with something, maybe the simple "All Things Plants Seed Swaps" will work and "Swaps" can be used internally. We don't to have have it figured out by the first official (i.e. non-beta) swaps. We'll get there.
That doesn't mean stop the idea-generation, though!
I like the ideas being thrown in the ring...we'll eventually find one that works, for sure.
