Why can't I edit post in Jobs?

Properly because you are a Trust Level 1 user: Basic Users.. see

For Trust Level 2 users: Member there is also..

Edit their own posts for up to 30 days after posting

I think this was introduced in the forum software to make new users not to edit to much in the beginning…

( Also there should be a explicite solved :white_check_mark: marker.. but i’m not sure about this in the jobs category. )
