To tweak an existing Wordpress site from PMPro to Memberpress. Courses run for fixed periods ie same start date for whole group, access for 5 month. One user can register for many courses. Time frames can overlap. Can only access paid-for courses. Course side is ok. I am struggling to get membership side (registration, access, protections) right. Also needs to integrate with Mailchimp - main database, discrete segment for each course group. Has worked successfully with PmPro but did not allow for one database / multi segments, and hence ability to have courses being promoted and or run concurrently. Old site is live - need to protect course and customer data. Courses are Art courses, 5 modules over 5 weeks, each module has 2 to 4 streamed videos, plus 1 to 3 downloadable pdf's. Users continue to access course for an additional 5 months. Access then ceases. Have one course now, releasing a second course in January 2016, and a third several months later. Each of these courses will be relaunched over time. (with new registration required for a customer to undertake a new course). Currently have active site and a mirror development site set up.
