national convention: annual or biannual?

[OPhiAGinger]

OPA has held an annual convention every year since the formation of our national organization in 1967. For the last ten years or so, we've toyed with the idea of moving to a biennial convention so that we could redirect some of the energy and money that goes into planning convention into other services to the members. But every time we get a little deeper into making that change, it just seems overwhelming. There are SOOO many things tied to that annual convention from the annual budget processes to the election cycles of national leaders to the delivery of leadership training. There are so many dependent parts of our programming that would be impacted, it just seems overwhelming to even consider.

Have any of you make this type of huge change? What advice can you share?
