The original author and brainfather of Yodl nemail(Karel Kubat)
(karel@icce.rug.nl) would very much like to to hear from you,
if you use Yodl in a commercial setting (beats my why).

Also, he likes to receive postcards, preferably from far-away places
(i take it that's from outside, or near the edges of, Europe).

His snailmail address:
