Great news for Don and all his hard work trying to get his apps back in the App Store:

The bottom line is that Apple will approve the latest app - SCOtutor for iBooks Author - which is the "re-engineered" version of the App, and will re-instate the other older versions of the Apps, but I will need to bring them up to the latest version.

I'll post links as soon as they're back in.

Update In honour of the app being back on the App Store, Don's made SCOtutor for iBooks Author free for the time being.
