If i add usergroup 1 to ACP->Application Forms->Application Form Settings they cannot see the types anymore. Does it not work if allow unregistered users in Application Types->Allowed Usergroups to see the application group but in Application Positions->Allowed Usergroups i do not allow unregistered to apply for the position?

All posts/threads made by guests are registrated users on my board (i've checked their name) and you cannot use the app addon without being logged in (although only usergoup 8 is set in ACP->Application Forms->Application Form Settings). Maybe they get logged off during filling out the application and thus the posts/threads are created by guests?

EDIT: Just tested it and if you log off while having the application opened and then submitting it, the post is made by guest. Can you implement a login check after hitting the submit button?
