I've never used WordPress multisite.
I'm using Wordpress single sites and I want to sync users and accounts more easily.
On my hosting account I have the main account as the root WP site in the CPanel.
All other sub sites (each with their own domain names) are of course installed in subfolders directly under the root.
/ sub site 1
/ sub site 2
/ sub site etc.
I'm beginning to wonder if I should stop and start over with all sites setup as WordPress multi sites--if that will let my users login once and have access to all sites.
As a note I use CMS Commander and ManageWP to manage many WordPress websites (including these), and I don't want to end up with an issue because of WP multisites.
Additionally I use s2Member Pro as my membership and content management tool.
I'm open to advice.
The biggest problem is I don't know what I don't know about WP multisite, and I'm afraid of building everything out again and discovering I've painted myself into a horrible corner I can't see today. For some reason I get the feeling that WP multisite is going away. And the last thing I want to do is try and move forward with a legacy tool.
