So I was reading through the wiki, and came across this:
http://wiki.roblox.com/index.php?title=Global_function
And I was interested, as it says that it can be called from any script. Is this not the same as a Module Script's function? Or are there differences?

No visible difference, however Roblox discourages the use of _G and shared. You should be using module functions instead of global functions.
