I maintain several websites; ask if you want URLs.

These personal pages just cover a narrow sub-set of my interests.

I now and again check the email sent to sb 'at' j12.org (you may use GPG Encryption if you wish to email me).

I use various Instant Message applications including Signal.

I Blog very occasionally.
