I would like to be able to prevent users from posting their own entries. Right now it's all or nothing - you can post everything or you can't post anything. It's a good control to prevent users from posting their own entries.
I would also like to be able to allow a user to only post entries made by specific users. For example, one of our employees should be able to post entries made by our associate, but should not be able to post payables, checks, or entries made by the VP of Finance.
