@Parisi - out of interest, how do you think Fabrik development gets funded, and how do you think it should get funded?
I may be wrong, but as far as I can tell, you last paid for a subscription in Sept of 2016. Like I said, I could be wrong, if you switched emails on your PayPal account, or I'm not reading our subs database correctly. And you may have received some free Pro support last year, when our sub expiration code was broken, and a lot of people never got expired out of the Pro group when their sub lapsed.
Even if I am wrong, that was the fairly typical way subs worked. People would sign up for a little while as they developed their app, then let the sub slide for a year or two or three, then come back when they needed to add some functionality, or updated J! / Fabrik and found an issue, etc. While their sub is active I'm providing support, but the sub only (partly) covered that support effort (I say partly, as subs have never been enough to fully cover the time it takes to provide support). But for the gaps in their sub, obviously they weren't contributing anything to the cost of continued development, bug fixing, feature enhancement, etc.
So, assuming I'm right about your sub, what you are saying is "I haven't contributed to Fabrik development for a couple of years, but I think someone else should have paid for <insert bug here> to be fixed", whether that "someone else" is other subscribers, or me. If I'm wrong, apologies, but the point still stands for most Fabrik users, who didn't maintain subscriptions for long periods of time, and simply expected development to continue, funded by others.
So subs just don't work. Which means we have to find a different way for Fabrik development to be funded. And the fairest way seems to me to be that if you find an issue you need fixing, or a feature you need adding, you pay for it. If more than one person has the same requirement, the cost can be shared. If that cost benefit doesn't work, and you can build your app cheaper yourself from scratch or using some other extension, then you can make that decision, and not use Fabrik.
Just FYI, on the issue of "the solution timeframe would be unknown", I've installed a ticketing / tracking extension in XenForo, which we will use if we do decide to go this route.
If you have other ideas, I'm interested in discussing them.
