Aegir help needed (Drupal provisioning)

I have installed Aegir (software for provisioning Drupal sites) on a dedicated server so that I can build many Drupal sites easily. I need help in two major areas: 1. Troubleshooting some errors in my Aegir queue. 2. Building install profiles from existing websites, so that new sites using a platform will be configured like an existing site. Please don't apply unless you've used Aegir before. Thanks!
