I have a multisite installation and want to accomplish the following using MarketPress, the Network+ plugin (and multi-db):
1. One Platform hosting multiple domains and subdomains using multisite plus the Network+ plugin. Example links are:
2. Single sign on to all "sites" (including main site, subdomains, additionaldomain and additional domains).
3. The same user profile viewable on all "sites" showing any special admin features from each site "sites" in a separate tab
4. Same ecommerce checkout for all "sites" (from one link such as “shop.mainsite.com”) where the user can shop from all sites (include the different domains) and pay via one checkout (the checkout pane will categorize the checkout items).
Is this possible?
