- I need to be able to have subscriber blog posts set

Hi - I need to be able to have subscriber blog posts set to draft status instead of published when they submit. I am using Buddyblog to allow subscribers to submit blogs. Is there a plugin that can help me achieve this? I was looking at the Moderation plugin but it appears to only allow moderators to flag content that is already posted, not set subscriber posts to draft status initially so that an administrator must first view it and then publish it. I guess I am looking for something more along the lines of a content management workflow plugin?
