Tosh,
Would you believe the vi editor and the standard g++ compiler on Linux is all I used

Sucker for punishment or what?!? I did cheat a bit and used The Gimp to create the pictures. Having started programming on an IBM green screen mainframe terminal many years ago, I'm still suspicious of all these gui interfaces that seem to be popping up
As for the ease of development of the site, it's been a long learning curve. Two years ago I started playing with Linux at home teaching myself C++ and it's kind of grown from there. HTML, javascript, MySQL, Sendmail, etc, have all been added to the mix. I do like a challenge
Regards
Stoney
