Welcome Bryan, glad to have you aboard!

Regarding the avatar, go to UserCP | Settings & Options | Edit Avatar, upload the file you want and it will resize the pic automatically.

Regarding uploading pictures, thats what Photo Albums are for and we'd love to seem 'em. Go the main forum view and click on the PHOTO ALBUMS forum. The first sticky message has instructions, click here to go straight there.

Also, I'm still looking for KOTM candidates, how about submitting your Model IV? See the KOTM (Kitfox of the month) forum for details.
