This is simple. You'll have to change your theme to a valentine's theme and the person with the most aesthetic theme wins. 

This will be judged on 11th February, so you only have to keep it on for that one day only (or more... your wish).

If you're interested, comment "THEME CONTEST" and tag 2 people. If you've already tagged in a different form, you still have to tag again (preferable different people) as we're only asking for 2 tags anyways.
