I'm User:Mike.lifeguard.
I use the toolserver to run a few IRC bots, along with some other users.
That project is known as stewardbots. In
addition, my SVN
repository has several client-side javascripts. You're probably looking for
my
remote.js
page, which many users include for their work on small
wikis.
I've also published the PGP key I use for mailing lists and other Wikimedia-related email.
