I just installed jomsocial to a joomla 3.4.2 website and i also use virtuemart 3.
Generally, client buys a package through virtuemart and then using a plugin i automatically place him to a specific usergroup, in which i will have different content.
1) Is it possible to have different content or profile to different joomla usergroups? If yes, can you give me some hints?
2) Is it possible to automatically take fields from virtuemart to jomsocial (fields like e-mail, telephone, username, password etc) in order then for the client not to have to reenter his data to jomsocial?
1. this is only possible for the profile fields content, you should enable multiple profile type to achive this.
2. not possible by default, you should create the plugin for this.
