If you are a regular Plus reader who enjoys the weird and wonderful world of mathematics, then you may be interested in helping Plus secure its future. We are launching a campaign to raise the funds we need for the continued development and production of Plus beyond 2009.

As you may know, Plus receives no statutory funding and is entirely supported by donations and grants. Our activities are made possible by the generosity of organisations and individuals committed to the future of mathematics education and to improving the public understanding of mathematics. However, our current core funding is due to end in March 2009, and we are therefore actively seeking further funds to sustain the future of Plus.

Please consider making a donation to Plus via our parent organisation, the Millennium Mathematics Project, based at the University of Cambridge. Your money will go towards the salary costs of our editorial staff (who write articles and news items, edit contributions by external authors, and produce podcasts), and our technical staff who maintain the website. Your contribution, no matter how big or small, will enable us to keep Plus as it is: interesting, intelligent, fun, and — very importantly — free of charge for all our readers.

There are three ways to give to Plus:

• Online: You can donate by credit card online via the University of Cambridge Development Office's secure site. Giving in this way means, if you wish, your donation can benefit from Gift Aid, making your gift worth even more to us at no extra cost to you. Please choose the option to support the Millennium Mathematics Project.

• By cheque: You can send a cheque made payable to The Cambridge Foundation together with a completed donation form to:

  Patrick Hawke-Smith
  University of Cambridge Development Office
  1 Quayside
  Bridge Street
  Cambridge CB5 8AB

  Giving via the Cambridge Foundation means that if you wish your donation can benefit from Gift Aid.

• Cambridge in America: If you are a US taxpayer you may prefer to donate via Cambridge in America. You can give online or by check using the Cambridge in America gift form. Please state when making your gift that you would like your donation to support the Millennium Mathematics Project and particularly Plus.

If you would like to discuss supporting the project in more detail, please contact Julia Hawkins at the Millennium Mathematics Project or Patrick Hawke-Smith at the University of Cambridge Development Office.

Thank you for your support!
