I overlooked the database-table jsn_users. The users belongs also to usergroups, stored into user_usergroup_map, and _viewlevels. And the (MD5) password is stored in _users. How to combine a export / new import?
Easy Profile is a young component and we definitely improve it.
So: Import plugin: we plan to improve with usergroups column and support for non UTF-8 characters. now the status is BETA Export plugin: when the import plugin is STABLE we make a export plugin in according with import format.
Unfortunately, these are not priority and I do not think we will quickly (I think on november)
