From the linked thread:
Donations don't add up to much and lead people to build up ultra high expectations which is why we stopped allowing/accepting donations. Projects & clients earned as a result of the plugin are minimal for us.
If there's no donation/payment mechanism, what other means of user support is there?
For now, the plugin is in hibernation. Once I get a bit more time and resources, I'll go ahead and pay Dan to push up some new fixes and features.
Perhaps "hibernation" should include removing the plug-in from the repository until it's stable and supported.
Meanwhile, I'll be disabling/deleting this plug-in and installing Backup Buddy at the suggestion of a colleague. I truly don't mind paying for a critical plug-in (I have several paid plug-ins already).
Thanks for letting me know what's going on with your software support.
