I wanted to let you know that we just upgraded to the latest version of WordPress MU, 126.96.36.199. There were some security enhancements made to make WordPress safer. Also, you can help keep your own site safer by using strong passwords that include upper and lowercase letters, symbols and numbers!
If you encounter any problems with your site that you think may come from this update, please let Derek or Linda know ASAP and we can look into the issue. Thanks!
