I'm trying to create 2 types of Sign In procedures, because I will have 2 different types of users. Is there any kind of module or plugin to solve this? Or i have to create my own module?
You can create different profile questions for different profile types in the Admin Panel on the Profile Questions page. This will allow your users to select a profile type such as fan or band and then a different set of questions will appear depending upon the type selected. For more information about the Profile Questions page, please see: http://support.socialengine.com/questions/156/Admin-Panel-Settings-Profile-Questions
