Sarah,
Welcome aboard!
How do you like the GAD? I A/B'd the 12-string version of that JF-30 against it's American progenitor and I thought the GAD was very nice. In any case, I thought it was head and shoulders above the other brands' 12s that were in the shop that day.
Again, welcome, and enjoy!
For the avatar picture, I believe I used Microsoft picture editor to downsize it to the necessary dimensions. Some bulletin boards do that for you automatically, but I guess LTG doesn't. If I recall, you're restricted to 100 pixels in either dimension -- I think anyp icture editor can save a picture out that way for you.
