Inquire at the Infodesk
How does this 1ct/s donation work?
Currently not at all. But if someone could build a little seconds counter or an app doing this, that would be great. Not a MM:SS timer, but an SSSS timer, to be converted into SS€SSct. If not, donation will just be approximate by your wild guess.
As Yoga is a related activity, there can be massage added as a bonus after.
