I just noticed that I forgot to write the costs of the swap... this is a bad thing at this time of the project, but it's usual to pay for the costs of shipping and handling the whole thing and I think it's not too much.
I would say that the best possibility of paying the fee of 3€ is through Paypal Now I don't know how many of you have a Paypal account. I think that it's the safer and more usual way of paying in the web. You only have to sign in and have an account there and they can send money to every person in the world who has an email address (and an account). You can get the information on the site. In this case my Paypal address for sending the money is:
For the participants who are in the European Union, please contact me per email firstname.lastname@example.org and I'll send them my IBAN and SWIF codes.
For the participants who are abroad and don't want to have Paypal the easier way is to put 5$ in the envelope and send them per mail together with the squares. I never had problems doing this.
You can also put 5€ in the envelope if you are from Europe and don't want to use the other possibilities.
Please send me an email asking for my address.
