We have just started using RS with 15 000 subscribers and 5 authors. There will be no restrictions on the subscribers but authors will be restricted to certain categories - that we have resolved already. The problem is with the amount of users the editing of posts under admin control is very, very slow as it needs to load all the users first. We have added custom functions to remove the authors meta-box but it is not helping at all. Is there a way to disable the loading of the subscribers(check-boxes) when editing under admin?
