fair enough if you arent willing to pay for tutes etc, but its always worth noting that the good stuff will always cost money, hell, even old pros like myself need to learn stuff and sometimes paying is the only way.
If youve learnt the basic principles of maya, like learn how to create objects, cut faces, extrude edges etc and so on then these things should be enough for now to get you on your way. Experiment on your own and see what you can come up with, also the maya help files have some light tutes to give you a grounding. Just by merely attending and watching the forums itself is a great way to improve ones skills.
But at the end of the day it will be your attitude and willingness to learn and share techniques that will get you to learn maya.
