Simple changes due to Ted reqs

[jeffchang5]

1. Home page reads "serving runner in the San Francisco peninsula...".
I think it should read "on" instead of "in" and capitalize the "P" in
peninsula.

Simple fix we can do

2. Home page has a "what we're about" button that links to our Meetup
site. If we want to expand on "what we're about', I think it should be
done on the same, or a separate web page. Having said that, I'm not
sure why we even have that button, as the rest of the Home web page
talks about the club.

Rashmi and I are thinking of reverting the button text to say "Run with us" so that the link to Meetup is more intuitive.
