TCat, don't hesitate to post your work. I'm still a few years ahead of you but that doesn't really matters. The important thing is to put one's heart into the music, not how many notes one can play.
And Vic, if you have a download limit then any file you load from the internet will add up to it. As these MP3s have a few megs you may want to check how much data you're allowed to download esp. if you're listen to a lot of music on the web or download videos and such. Web radio is also a huge amount of data.
