A big hearty Thanks out to everyone that helped me out with my Regular Expressions tutorial:
jdporter, gaal, ww, ysth, jonadab, hossman, tye, ww, Solo, Not_a_Number, muba & demerphq.
Especially jdporter for our conversations & his patience and the idea of this form of thanking everyone for taking the time to interact with my nodes.
if you're on this list, and you've suddenly found extra XP points one day, that's cause each day I'm blowing my votes on one of these members, .. my way of saying thanks.. for what that's worth. It's my morning ritual these days.

BELOW IS JUST A MIND GAME,
PAY IT NO HEED, but if you tinker and find it gives you 0 through 10, let me know! It's been noted it should not give consistent results across different OS's or computers.
