H Barry, you would need to develop a system that hooks into the API of Both but which is the core CRM and interacts with both sites.
I don't know if this would work, but one site two could he just change the id of the login forms to match the Site One?
Again, not sure if it's possible just a thought.
No because you still have two different CRM's and site 2 wont run site 1's informaiton etc
You need to do it manually with the CRM spreadsheets daily (eeek) or API.
Thanks for the feedback.
