Your catalogue??

I upload my songs to Ultimate Guitar:

The stuff I write is done like this... I punch in chords in a program called Band-in-a-Box, and from there, when the song is done, I save each track (drums, bass, etc.) as a wave file, which I import into GT4.  It's rare that I don't come up with a riff or song while practicing, and so every practice session pretty much is the writing of a song or the recording of it.  And so, I do record my riffs as they occur during practice.  When it comes to vocal type songs and a melody, I tend to hum those into a tape recorder for later use.  Sometimes I need some kind of link, bridge or whatever in a song... in a minor or major key, and will go through some of my recorded things to see if something is appropriate.  But when it comes to guitar riffs and hooks, usually something pops up during practice and I don't keep a catalog of those.
