A: 1. Should be very easy. You can chain tasks, eg Once article creator has finished running it starts the WP poster. You only need to setup the WP poster once and it should be re-usable.

2. There is no limit. SCM uses JSON API to connect with your WP blogs and upload posts.

If there is any feature or workflow limitation with SCM that makes it hard for you to automate the posting please let me know and we can figure out a solution.
