hey jaash,
Yeah, I'm doing great. Really excited for my first year of College at the University of Washington (start September 29th).
Anyways, this tool looks pretty cool. I code in notepad, so I like doing everything by hand and using as little of these little tools as possible. While I do think it's good to use when you're in a jam and can't figure out a regular expression, I think it's important to just try out your reg ex's and see what works and what doesn't. They're confusing at first (i still have a hell of a time with them. weedpacket and xblue are the experts here on regular expressions). I personally like just going at it myself. A lot of people will disagree. Anyways, I'm sure some people will find this helpful.
BTW: Since you're not actually asking for any help with a problem, but rather posting some information, I'm going to move this to the echo lounge for you.
