How does it work?
This is an informal request for a financial pledge of this crowdfunding campaign. You will get an official confirmation about the pledged amount, which will become a binding contract as soon as the first milestone is reached. You will then get an invoice about the amount of your pledge. Contractual partner will be Oliver Klee, the official maintainer of the extension seminars.
At any time, it is possible to increase the amount of your pledge. You cannot withdraw or lower your pledge, though.
In case no milestone will be reached until end of September 2019, you will not get an invoice and the contract becomes obsolete.
