@Blueberry: Wow thanks. I feel like such a newb for not noticing the Search tab. Now that I know, it seems so obvious... Haha! And good point that it would probably be more of a hassle to readjust the seat every time I ride.

@Sundial: Thank you for the info on the bike chain method. I may try that! Theft is pretty high here in the big city. I may need to take whatever precautions I can!
