The best way of contacting Stuart Langridge is by email to
sil@kryogenix.org.
However, I can, sometimes, be caught in real time, using various IM services.
On MSN, I'm
aquariusthegreat@hotmail.com, on AIM/iChat I'm
aquariusthegreat,
on Jabber/GoogleTalk I'm
stuart.langridge@gmail.com, and on Yahoo's IM I'm
aquarius_the_great, all done using
Gaim Pidgin. You should also drop me a line if you're
going to be in Stourbridge in
the West Midlands in the UK and we'll get a beer or something.
If none of these things seem to work, then you can try the LugRadio forums. I'll probably have posted there recently, and you can get my email address from there. I'm also sometimes on IRC, on freenode, probably in the #lugradio channel, as aquarius.
I'm also on Twitter and Whoisi and Identi.ca and del.icio.us and LinkedIn and FriendFeed and Last.fm and Pownce and Flickr.
As a last resort, lean out of your window and shout "Stuart!" at the top of your voice. I might hear you, you never know. :-)
