Recovering (or creating a new) admin account Our developer hasn't been able to recover his password for the account he used to setup the site, and now he's non-responsive. The site is on my server and I have full access, but his account is the only one we setup.

We're not able to add new companies until we can either recover the account or setup a new one.
Download and install a fresh copy of Craft from http://buildwithcraft.com somewhere (doesn't matter if it's the same computer your existing site is on or not).
During installation, remember the password you entered when setting up the user.
Open the database and look in the craft_users table. Copy what's in the password column for the user that the installer created over to the password column in the craft_users table for the site you're trying to recover.
If the locked, suspended, pending or archived columns have 1 in them, set them to 0.
If lockoutDate and/or lastInvalidLoginDate have values in them, delete them.
Login to the site you're trying to recover with the password you created in #2.
