A security-related upgrade to Moodle has been released recently. I feel that this upgrade needs to be installed at Converse sooner rather than later. Accordingly, I will take the site offline from 6-7 AM tomorrow morning, Wednesday 2/23/11, to perform this upgrade. Version upgrades (like this one) are normally pretty painless, so the site should be back to normal (except for being a little bit more secure) by 7:00 AM.
I apologize for any inconvenience.
