Hi,
It's hard to say. The review process takes weeks, and that supposes there are no surprises (like you need to redo half of the plugin because something is not to their liking). And before that, we need to setup an online website they can access with the plugin etc, all configured with instructions... I was a bit disheartened when reading all this and put this on the back burner. I need to get motivated again to do all that work so that we can rerelease it with the certification. But even if we started today (which we won't because we're working on other things at the moment), it would require at least a month I think.
