First Soenke, thanks for setting these topic specific forums up, it certainly is a great improvement over this single threaded e-mail conversation.
Second in reply, I already have a better solution already worked out in some detail currently in LaTeX/pdf. It would be probably better to put such stuff in a wiki or something. I could offer to setup a media wiki installation on my crappy home server, but I am afraid it would not scale well and only has a dyndns domain. I'll do it, if nobody has a better solution.
P.S.: Is the "I forgot my password" feature of this forum actually working? I don't seem to get any password-reset e-mail :-(
