Hi there. Can you explain what do you mean by scrap (scrapping what exactly) and how do user get invited? The mechanism for it, sort to speak. For the second part, is there an API for that central database? Is this extension from scratch, or maybe some work is already done? If so, can I see the source code?
Also, when do you plan to start the project and when is the deadline, if there is one?
Anyway, feel free to hit me up so we can talk more about this. I am very responsive. All the best
