Just wondering if anyone here plays any instruments...and if you're any good at it

I play:
-Piano(My mom had me take lessons starting when I was 8. At the time I didn't want to do it, but now I'm glad I did )
-Viola(I played it for orchestra for school in 5th and 6th grade, I wasn't really that good at it )
-Violin(I switched to violin from viola because it seemed easier. Violin plays treble clef and viola plays its own weird clef, so I figured with a violin i could play the songs in the piano books i already had)
-Guitar(i think this is how it happened...one day like a year or two ago, my dad found some tabs online and he had to run to the store quick or something, i don't remember, but he left the computer on and it still had the page with the tabs on and i tried it and i was like, hey this is easy...and fun! I'm working on chords right now, I have a few down pretty well)
-Mandolin(here are a few pics if you don't know what they are. My dad got one recently because he's started to like the whole bluegrass thing and it's tuned exactly like a violin, the strings are G D A E, so I've been playing some songs from my piano books and some that I've found online)

also, 8notes.com has some popular riffs. I've found some good ones there.
