If there is wish to donate Kotkaklubi and somehow you do not like leetchi money pot logic, there is still open direct donation account of Kotkaklkubi:
About donators name and contacts I have side opinion. We have got donations into that above mentioned account and I feel it to be polite to thank every donator personally. Here is not a shop with anonymous customers I think. Sometimes it takes a lot of time to find contact of certain kind person. We can see the name in bank transfer data, but very difficult is to find right person to thank her/him if from Germany the donation is coming from Anne Schmidt or Alex Bauer...
Second, if we know the name of donator, it is possible to get back some tax from donated sum for donator. I don't know exactly, how it works but basically should.
Leetchi donations money pot is organized by Jo and linked to nice Book about Karl, so it is a bit different line, but we can for sure give to Jo information about direct donations in Kotkaklubi account to enable virtual ownership of the book for direct doantors. For me it seems that leetchi payments are easier to make as usual international bank transfer (if coming outside Estonia).
Finally, if something seems strange for you, you can skip the process.
