Yes, I was an Agile Manifesto signatory!

Yes, I was a relatively early signatory to the Agile Manifesto.  I "signed" in the 19 May to 20 June, 2003, time period.  I did my first test-driven development (TDD) using the SUnit testing framework in the Smalltalk programming language.  I was immediately attracted to "agile" and TDD because I had been developing software for many years and well understood the value of the new approaches.  I am still agile and I still recommend TDD, although I am now aware that there are many areas of software engineering where TDD is not yet possible.  As far as agile goes, I do not stand for no process, but for "just enough" process!
