…we are launching

  Electronic Proceedings in Theoretic Computer Science (EPTCS)

a new international refereed open access venue for the rapid
electronic publication of the proceedings of workshops and
conferences, and of festschrifts, etc, in the general area of
theoretical computer science, broadly construed.

This is exciting news! I’m even willing to overlook the fact the plural of ‘festschrift’ is ‘festschriften’, not ‘festschrifts’.
