This is the Entity Relationship Diagram I have created for my web application (based on Oracle APEX project). Two type of users can sign up and login and each user has his/her own profile and privileges (Webbeheerder & Expert).
But the problem is how can I make a table called "TypeUser" for example and when the user wants to sign up, he will be asked what kind of user he/she is. So no separate sign up/login pages for each group/type user. I know there must come a new table, but I don’t know how should I exactly solve this.
I'll appreciate your help and suggestions. Thanks a lot.
PS. Any other suggestions about this data model of a web application where Web masters can share the link of their website and ask Web designers for feedback. Web designers can comment on a link and rate it. Each of these user groups can view the other's profile ( so there's also a dedicated profile page)? Improvements?
Incorporating the the answer of LironCareto results in the following diagram:
