As part of their 125th anniversary celebrations, Wimbledon are running a competition to win Centre Court & Court 3 tickets for this year's Championships. If you are on twitter or Facebook, you will no doubt know this already, but I am posting this in case others are interested too.

Each week on a different day of the week, they post a clue on twitter http://twitter.com/#!/wimbledon and Facebook and you then have 24 hours to enter. Solving the clue (not quite as trivial as your average TV phone-in comp these days, but still quite easy if you are familiar with the Wimbledon site) lets you find which page of the site the link to that week's entry form is on and you then have to answer another question, the answer to which you can find in the relevant section of the site.

I thought I had posted this yesterday (not sure where it disappeared to or if I failed to click Submit Post - it was a bit of a hectic day, so I wouldn't be too surprised ... ) so unfortunately this entries for this week's competition have already closed, but I have started this thread anyway so one of us can quickly post reminders when the remaining weekly competitions open.
