I start using moodle since 1.6 as administrator..... . I just migrate my 1.9 to 2.0. Now is 1 week already i explore the system...... i find that so many problem to handle a role exspecially in system roles. Now for me 2.0 is not admin friendly anymore..... so many role button is not working....when click its past me to blank page. ((
I think better i migrate back to 1.9........ the problem is....i have to handle mostly 2000 users... so ist not easy for migration.
