Changes

There must be an active semester, before any other functions can be used. A student may not login if there is no active semester. Administrators are forced to add, or extend a semester if there is no active one. Once a semester has been added, it may not be deleted, only extended. The only time a semester's start date may be edited is when there are no projects (and therefore no students) associated with the semester ID. To edit the semester's start date, make sure to delete all projects associated with the semester (see [[#Deleting_a_Project|Section 3.2.1.3 Deleting a Project]], and then edit the semester's start date.
