"BETA-TESTER" searched!

I search for the "online calculations" on these homepage "beta tester", which intensively tests the programs and me improvement suggestions by E-Mail sends.

The work of the "beta tester" spent on it; is unfortunately NOT possible in the context of my possibilities to honor!

In advance I would like to thank you all, which took part as "beta testers" for this and/or to take part!
