sharing post with other plugin

I am already using Geodirectory for my Events. Their plugin does not sell tickets.

I am also on a multi-site network.

I need a ticket system for my site. I have thought of creating a sub-domain ticket.sub-domain to sell tickets.

My concern is how to share the event postings in your plugin that require ticket sales without duplicate entry.

One idea is to show a link from the “event posting success” page to the tickets.sub-domain.com. If their event “is” selling tickets they could then set up the ticketing system.

Kind regards and thank you for your idea sharing also.
