Hmmmmmmm, this is a very good point @JammyDodger. Admittedly, the decision to grant level 3 to all the users was made more than a year ago, and you have changed and improved many things since then. Looking at your comparative table of what users at each trust level can do:
It appears that if our ordinary users are starting at level 2 they would not be at a noticeable disadvantage. We are already investing in education our level 4s - Leaders to be able to manage the content in categories and work with tags. We have to discuss this with our team.
But (and you know us by now) the next question would be: if we decide to downgrade our user base from level 3 to level 2 (about 250 users and growing) what would be the easiest way to do that?
Thanks for you help
