Use GPG-encrypted mails (with key as published) for your first contact, I accept only mails from known addresses and encrypted ones to avoid spam. Unsolicited commercial e-mails (also known as spam) are not welcome!, see also Spamcop.
Please do not send documents in a volatile, proprietary format, e.g. Microsoft's Word, etc. as I am unable to process them. Use Postscript or PDF instead. DVI and TeX sources are welcome as well as plain text (ASCII, Latin1 or UTF-8 encoded).
Check it! Check it!
