Hi!
Im Jeff from the UK
I last used Corona about 4 years ago for one app, and have forgotten just about everything. 
(Use it or lose it, as they say…)
I’ve loaded up my old code for the app in the latest Corona, (and nothing runs), so it’s going to be fun time trying to work out just how much has changed.
Im hoping to put together a new paid-for app (there won’t be enough users to make ads pay for it) , and maybe an Android version too.
