Dear all, who knocked on our doors with donations, which we could not process.
As TUG accepted to collected donations on our behalf we changed the link on the LyX donation
page. I hope it will work now. Thanks for TUG's help and sorry for taking (literally)
years to act...

BCC-ing all the kind souls who repeatedly asked on this list :)
