Welcome!
Not enough classical players around here, interested to hear you progress as you get into that world of technique (it intimidates me anyways ?)
At the very bottom of the GFSA home page, you'll see a "active in last 15mins" list of members logged in. If you click on your name, you'll be re-directed to your profile, from there (on the left hand side) you'll find a link "Forum Profile Information" where the signature info is stored.
Though, it's cooler to start a new thread with your gear (even in this thread) - that way you can upload some pics...the common saying is "pics or it didn't happen". Uploading pics, if you don't have a internet photo hosting place - you can upload pics on GFSA :
