Um. Me. Iain Truskett. Can be found as either Spoon or Koschei around the place, and as Braxiatel in rare circumstances. Um. Cool. Ta.

My perl svn repository [dellah.org] if you want bits of code by me. Also see dellah.org [dellah.org] for most of them in action.

My friends [perl.org], foes [perl.org], fans [perl.org], and freaks [perl.org]. And you can see what my friends are journalling [perl.org].

And everybody's journals [perl.org] (in order of updating).
