TIP: for website owners: If you are running ads on your page to generate income, do not bombard people with as many ads as you can display at one time. It is annoying, distracting, and the very first thing we do is leave the page.

TIP: for iPhone users: Did you know that if you make a typo and don't spot it until you've nearly finished your message, you don't have to backspace all the way back to the error. Just hold your spacebar down and drag the pointer to the spot of the error and fix it.
