A week ago, I messaged a staff member / Plugin poster (who has posted the plugin before a bit back) asking if they still posted plugins to which they said yes and then I asked if he didn't mind to make a post or send the plugin through Convos of the "Plugins Per World" plugin but then he blanked...
@DJPlayz, not worth it, I ended up trying both and they've got problems. For example ultimate blockregen has no tracking and just uses bukkit scheduler which ends up out of sync and half generating the mines so I'm just making a custom one. If you want it when it's done flick me a DM and I'll give you a copy.
