I have quite a few modifications running on my site and based on that experience I have a suggestion on the modification eco-system for Xenforo. Instead of going the vbulletin route of anyone releasing a mod, I strongly suggest that Xenforo setup an Apple app-store type system.
The idea is that every modification should be approved by the Xenforo team who will check for full compatibility to the core system. Xenforo will get a cut on the revenues so they will also ensure that the developers offer support etc.
In the vbulletin system, many of mods don't work when vbulletin upgrades their version and hence I had to wait until all my mods are updated to the latest version before I can switch. Secondly, some of the mod authors disappear and it is hard to get any kind of support from them (even if I am willing to pay hefty for it). An appstore type solution solves all those problems.
What are all your thoughts on it?
