Lots of typos on the front page. Also, bad math. 28638 received over 23634 sent is a 200.03% return rate? No. "Sent" and "received" are already very ambiguous

Lots of typos on the front page. Also, bad math. 28638 received over 23634 sent is a 200.03% return rate? No. "Sent" and "received" are already very ambiguous - is "sent" what I sent you or what you sent me? But either way, it doesn't work out to a two-fold return.
