"Over the last few months, I've found that I'd developed a new reflex action: typing in my browser whenever I was confronted with a RegEx problem! Now that I'm my own boss (I went freelance 3 months ago, setting up Seaturtle Software Ltd), I'm free to spend company money how I like, and what better way than supporting fellow software developers! Thanks for a great tool."
