I am semi-retired from SFF.SE and don't always regularly visit Q&As or Meta, though I do read my Inbox.
The surest way of contacting me is via e-mail: ahch.to.1632 "AT" gmail "DOT" com
I've still severely curtailed my participation on the site, but some of the site changes which occurred in 2016, especially the quality of newly elected moderators have made me far more willing to engage in limited participation.
On the site, I have tag badges in the following tags. Make of it what you will :)
