As far as I can tell, the card only needs to be active when you register. My account continues to work long after the card has been inactive with a zero balance.
Creating an account is not all that bad. You only need to do it once and Mailinator email address are accepted :)
Good idea, but make the workdays of everyday shorter so you still get same amount of hours of work done each day. I much prefer this method since whatever you were working on is still fresh in your head.
Also, some editors have their own rule for how many spaces a tab makes - some use 3 and some use 4 - or if you're like my designer co-worker, you manually use the space bar arbitrary. Gave me a big headache when looking for matching css selectors.
