Eoin,
The renewal discount works for any of our extensions, so you'd be able to extend just JFBConnect if you want. For those who have the social bundle when the LinkedIn functionality is rolled into JFBConnect, we'll be moving their subscription to JFBConnect and extending that subscription with extra time (they'll be going from a subscription that was for 2 extensions for 6 months to only one, so the time remaining will be at least doubled, though we'll be throwing some extra time in as well).. I hope that makes sense.
So, it's up to you which way to go. We are not planning any major changes to JLinked going forward, though there may be a minor bug release or something like that. Honestly, in your position, I'd say go for JFBConnect. *IF* we release some big change to JLinked or a major bug, we'll provide it publicly. As a 'former' user of JLinked, if you contacted us, I'm sure we'd give you a copy of the new release as well..
It's a weird transition, we know.. but that's part of the reason we announced it in advance. We wanted to get user feedback and make sure everyone knew the changes that were afoot.
If you have any questions, comments, or general feedback, as always, just let us know.
Thanks,
Alex
