The weissensing usage is free and will stay that way. The operation of the server, the databases, and the storage amounts to a bit less than 8 Euros per month, not counting the time that I spend to maintain everything.

Here you can help to bring up the required amount of money.

Equally helpful and appreciated is any kind of feedback. Is weissensing easy to use? Do you have any improvement ideas? Or a simple "Well done!"
