Many of us rent multiple spaces all over the grid and knowing when payments are due can be a nightmare.
Here in Mainland London, we have a free to use service, "My Rentals Finder" to make life just a little easier.
Simply click the board and you will receive a private IM that lists all your rentals, everywhere on the grid, informing you of the time remaining, the landlords name and a Slurl so you can TP directly to the rent box.
This system is located by the entrance to the tube station in Soho. Click here to visit and try it for yourself.
