TSUL.net is based onGoogle Apps. The services used include mail, calendar, document and blogger.
Most settings are user friendly on dashboard. However, blogger will require separate setup. Go to blogger.com, and create a new blog and navigate to publishing tab in settings. Follow the instructions there. (Maybe this could be a feature in Google Apps in the future. ;))
Also, it is better to have fixed URL (instead of redirection) for mail, calendar, and document services.
