Thanks, Mark, but I’m not sure what you exactly said.
If you mean I ask Xenforo to help me, then that’s pretty much clear they won’t do anything about it. It’s like someone asks you to help him/her to migrate from bbpress to Xenforo. Will you do it? of course not! Why should they help me upgrade your plugin in order to support migrating from their latest version of forum software to yours? (logically they will help those who are using your forum, to migrate to their forum. Not the other way around)
But if I misunderstood, would you mind clarifying it, please?
