Online Tea-making rotas (and Holiday scheduling)

>> I Made It Last
>> Who’s Off?
Here are a couple of sites to help streamline a couple of important parts of office life.
I Made It Last is an automatic online tea rota designed to ensure that all team-members take their turn at getting the hot drinks in. Register by entering a user name, Password, Email address, and your chosen beverage - plus milk & sugar requirements. When you want a drink, just click on ‘Order’ and as soon as a set number of orders have been placed, the site sends an email to the next name on the rota, telling him or her "it's your turn to make the drinks".
Who’s Off is probably the more genuinely useful (and more sophisticated) service. It’s a fully-featured online staff holiday planner, which lets employees submit their leave requests online, and automatically calculates their remaining holiday allowance and whether their requested dates clash with leave already booked by colleagues.
