As said it is not recommended to use the extension on a live forum. If time permitted me, I would have already submitted the extension to the extension database, but I have not yet been in the ability to test the conversion from phpBB 3.0 to phpBB 3.1, which prevents me from submitting.
That said, the rest of the extension will most likely not undergo any changes for the first stable submission (it is actually stable as far as I tested it, which is all but the conversion). So if you know what you're doing and you might want to check if the extension works on a local copy of your forum. If it does, it probably will work on your live forum too, no guarantees though.
