Well, the true picture is beginning to emerge. Moodle started as a great resource, and has 'blossomed' into a Juganaut , taking on new Modules and resources, and beginning to become the VLE that everyone is looking for ...a resource that meets the needs of everyone! The exponential expansion of Moodle suggests that the developments are becoming more and more attractive to users with different agendas/needs. I don't have a problem with this rate of expansion at all, except that my little venture into VLE now has to expand into a quest for new sources of money to make it successful in our cash-strapped school.
Catch-22 ... make sure that your cash-strapped school can find new funding to pay for the hosting requirements for Moodle!
Some guidance/advice will certainly be needed, related to resource requirements. Users should not be put in a position where they will be told later of the 'problems' with expansion.
There are a few possible solutions, for cash-strapped schools.
1. There is no problem at all in spreading a number of Moodle's around the world, hosted on a number of different servers. Why put all your eggs into one basket, and then wait for doomsday/armageddon?
2. Each department should be encouraged to take on board their own Moode resource (site), rather than to depend on one person trying to do everything. Goodness, the learning curve is not that steep.
3. Another partial solution is to be very selective with the Modules, and to only install the ones you will need at the time.
Also, unless there is a very real need, the use of Moodle involving full class participation at any instant might not be entirely necessary or desirable. The use of Moodle can be spread along the 24/7 universe, not just in a 1 hour class slot. Therein is the great beauty of Moodle.
