Kind of in the vein of what Arya said, more support when it comes to rush and risk management, especially for smaller chapters. We're losing one of our oldest chapters at the end of the year because of this, and I honestly think that we have enough money to provide more support, but we just don't.
Also, make it easier to change policies on the local level. I'm not talking about things like shacking and drinking policies (haha) but more in line with judicial things and the way things are run. At the beginning of this year in our chapter, our standards board was able to kick out an officer that they felt was not doing an adequate job (not for "standards"-related behavior, either -- it had to do with a decision she made for her office) even though the entire rest of the chapter disagreed with them. When we called our advisor about it she basically told us that we had no recourse because Tri Delta's national policies were set up to let standards could do whatever they wanted and they couldn't be changed -- not okay.
We got over the drama, but a lot of people became disillusioned and frustrated with national policies that they perceived as being "unfair" (including me, could you tell?
) and it all could have been avoided if we'd just been given a chance to contest standard's decision.
