Hello, im starting t oplay with userman, however im on some dead ends, since im not sure if i can not find a function or its just not there:

(self)user signup...is this possible? to have a signup in the login page?

payment API...where is the docs? how can i develop a gateway?

if there is no api, is there any way, external to userman web page to add users?

did you find a solution yet? ...because I'm sitting with the same problem
