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 Empathy. 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 IRC, on freenode, probably in the #ubuntuone channel, as aquarius.
I'm also on Google+ and Twitter and Whoisi and Identi.ca and del.icio.us and LinkedIn and FriendFeed and Last.fm and Pownce and Flickr and Dopplr.
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. :-)
