....of these 4 options:
Life (bare in mind we're leaving uniservitys old system)
Moodle (my personal opinion here is that we will never have the technical time to support this)
MyBigCampus (we're a lightspeed customer so this is free)
Regardless of whether you've used more than one of those i'd like the pros and cons of what you have used, even better if you can compare one to another though.
