I am building a site that will have three levels of members (i.e. 0, 1, and 2), all of which will be free. There’s no problem with creating the necessary registration forms, but how can I set up modification forms?
In other words, when logged in, level 0 will need the option to select levels 1 or 2; level 1 will need to be able to select 0 or 2; and level 2 will need to be able to select 0 or 1.
The problem is that the modification forms want a payment processor to be set up, even if the new levels will be free, while the free registration form just won’t work for modifications.
So what do you suggest?
