The Membership plugin has an option to use Invite Codes, and those codes can be set to be removed from the system upon being used once.
We are about to send out a newsletter alerting our subscribers that the site is now open for registration. We will use eNewsletter for this.
Can anyone imagine a way to send a different invite code to each of our subscribers, either through eNewsletter or some plugin that might exist? Of course if it required a different plugin, we could export our mailing list from eNewsletter and import it elsewhere.
Thanks so much for any help or insight.
