hi. this popped up while trying to debug something else. wp 3.0.3, bp 1.2.6, supporter 2.2.4.
it seems that the super admin cannot increase "Site Upload Space Quota" in the edit sites screen. when trying to increase the quota above the supporter limit, nothing happens.
ideally, the super admin would be able to increase the limit on an ad hoc basis. this way, we could potentially charge for additional space (via some simple paypal buttons).
