When I joined, I did not think my app would be accepted and just thought I would try. However it was accepted pretty quickly and I did not have to submit more than one. Although I do not know, I think that what other editors have said is true - those 90% probably contain bad spelling and grammar, no sites or just rubbish. The application is slightly more complicated now but I doubt that will deter anyone. IMO the application system certainly does not need to be any easier and, however much it is, the percentage rejected will always be high because on any online form many some people will just put anything for the sake of it. Anyone who really wants to be an editor can be with a little effort.
