As a follow-up of T281926, ptwiki community requires some modifications on the extended confirmed user group. They are two:
- Make the actual "extendedconfirmed" an implicit user group, called "autoextendedconfirmed" with the same criteria for autopromotion (30 days, 500 edits);
- Create a new (normal) group called "extendedconfirmed" with the same rights but with no auto promotion;
