From now on anyone who solved 1000 puzzles or more will receive the title 'experienced puzzler'. Anyone who created 100 puzzles or more will receive the title 'experienced author'.
For now the titles are handed out manually, so if you have reached one of these milestones and you did not receive your title, let me know.
You can get both of them, like Bram and connect4 did. Only they are also judge, so that is what is shown in their miniprofile. If they would not have been judges, it would have said 'experienced author' in the miniprofile. On someone's full profile it shows all the titles earned.
