I'd like to create a frontend form by which regular subscribers can submit map markers (and descriptive info) to a mashup map I'm creating. I'm using the mappress pro plugin rather than the wpmudev google map plugin just because it was already installed. Anyway, I'm thinking this can be accomplished with custompress? Anything I need to know to make the two plugins play nice together? Will custompress allow subscribers to submit map markers on a mappress map, and have the submission held pending my review?
