I started using mIRC when I was 13 or so (I'm 24 today), back when it was still version 5.x.
I used it for years without registering, reason being at that age I didn't really have a method of paying for it and back then you could de-activate the pop-up window at startup for non-registered copies so it wasn't a nuisance.
I finally registered for it on December 31st, 2005 (I still have the original Email I was sent upon registration; I was 19 at the time), some months after having been at my first full-time job and having registered for PayPal to pay for it.
It's been a very wonderful, legally registered and paid for, tool since then.
