And I forgot the GD from that post as well

GD

That's similar to how I managed to get U215500 for the GP, although it wasn't as much as a rush!

RhoMuNuQ

I only rushed as I wanted to be sure that I got them


And now that we do have residency, what exactly is the plan for their use?

I've got absolutely no idea!

RhoMuNuQ

Anyone know who got A1000000?

A1000000 doesn't exist - the closest A-numbers on either side of it were taken by the Group Persona.

RhoMuNuQ

No such number - hence it doesn't turn into a link, and will get an error if you try and load it. The trick is, the last digit of each A-number is a 'check-digit', so if you want, say, the forty-second entry, you take 42, add the appropriate extra digit, and get A423.

And if you really want to know, the check digit has to be such that adding the digits up makes 9, 19, or somethingty-9. Or, to be *really* -y about it:
(sum of digits) mod 10 = 9

and here's a Perl one-liner []:
foreach $digit (@digits) {$sum+=$digit}; return ($sum % 10 == 9) ? 'Valid' : 'Invalid';
[I *think* that would work, anyway... ]

I bow to your supreme geekiness.

Glad to be of service

Just a thought - was it you who got U200000 and never used it for anything as well?

B

Who are you asking?

The bugfinders in general, but mostly you, come to think of it.

No I was nothing to do with U2000000. As far as I can remember it was grabbed at about 6am GMT one weekday morning, so there was no way I was going to be around at that time to get in on the action

That's nothing to do with me - before my time, as you can see from my U-number.

U200000

Sorry, I got over enthusiastic with the zero button back there

Well, U2000000 is *after* my time.

RhoMuNuQ

That one _will_ take its time coming around.
