Also, WHMCS barely provides any extra value to MOFH, besides not beeing compatible pretty much at all at this point, and requiring a whole lot of work. To get Xera to an efficient and secure state would take quite a lot of work. Youll also have to imagine the additional server load itd cost them. iFastNet hosts millions, if not billions of pages.   If they really want a new feature, they can just implement it into vPanel, which would be the proper way of doing it in the first place. But since they still want to promote paid hosting, they obviously wont do that.   iFastNet offers some of the most generous Free Hosting. Its free - dont complain about it (especially since they still allow these features to be implemented externally)

What hosting? Byet free hosting? Theirs party reseller free hosting? Premium hosting? VPS? Please provide more detail. Also, wrong category. 

It would though. vP is comply custom, it’s not “grab an API key and it works”, it would take multiple weeks to improve the current system. And they don’t care (and there really is no reason to) since resellers like IF and TH have custom systems that will be better than anything iFN themselves can make in a month. And since the core service is exactly the same, iFN gets no additional revenue, there is pretty much no point in adding more competition, as they would just be doing a bunch of hard work to compete with themselves. 

Satın almış olduğum bir domain var bunu sizin hostinginizle eşleştirmek istiyorum domain ekleme bölümünü bulamadım ve asıl ekleyeceğimi bilmiyorum.   TRANSLATION: I have a domain that I purchased and I want to match it with your hosting. I couldn't find the add domain section and I don't know how to add it.

i know but alone just integrating something like WHMCS via Softacoulus or even any panel customization would already be a huge plus and wouldnt cost like any time. they just used Vanilla MOFH Package and called it a day which i think is kinda sad for the official Free Hosting
