The two best ways of contacting me are e-mail and my feedback page.

Recently, I have been getting a lot of unsolicited e-mail (advertisements, also known as spam). Therefore I am now filtering out part of the incoming mail into a low-priority mailbox which I check usually once a day. In particular, please avoid Subject: lines which use only CAPITAL letters, avoid multiple question marks (???) and exclamation marks (!!!), and please do not send mail to my old addresses.

If you need to send encrypted correspondence, or verify my PGP signature, you can find my PGP public key at this link.

My phone number in Finland is +(358)-9-191-8690.
The fax number is +(358)-9-191-8681.
Our time zone is two hours (three hours in the summer) east (earlier) of Greenwich.

If you wish to send me the old-fashioned surface mail, you may use this address:

P.O.Box 9 (Siltavuorenpenger 20J)
