@RK, That’s very kind of you. But allow me to choose neither, especially that I didn’t do a big deal in the site hacking issue.

On the other hand, I’ll be on the watch for the emoticons.

@Hex- early bird cathes the worm
But, since you really helped me out with the site hacking issue, if you’d like the RUNES or PDF, shoot me an email info@smart-kit.com and I’ll get one out to you this weekend

emoticons coming soon, I promise!

Looks like by the time I first saw the puzzle, 6 correct answers had already been submitted 8-)

I’ll have to settle with a pat on the back

RK, when are you going to include a link on puzzle pages to the emoticons page so we can easily express our funny emotions correctly?

Well done to those of you who got it. I really didn’t know if it would be too easy, too tough, or somewhere in between. I hope you all enjoyed the puzzle.

51
or I should say LI?
the numbers in roman numerals are all represented with two letters only, that is:
XI, XV, XX, XL, LV, LX, XC
the only one left that can be represented in two roman numerals is LI–51

90 – XC

The last number is 51. They are all two-digit numbers with two-digit roman numerals as well.

They have two digits both when expressed in decimal and as Roman Numerals:

XI XV XX XL LV LX XC

51 (LI) is the only other number that shares this property.
