Please encrypt your e-mails with PGP if you can, my public key is here. (There are beginner guides on how to set up PGP and Thunderbird in 30-60 minutes for Linux-based systems, Windows and Mac OS X).
If you could attach your own public PGP key in the first e-mail you send me, it would make it a lot easier to answer. I do not check/answer e-mails that often, but I try to do it at least once a week - so you'll need to have some patience.
Note that my previous @bitmessage.ch e-mail address is obsolete, since that provider has been terminated.
