# Days after Spawn: unknown - spawns were never observed, so no way to tell.

    Thanks Tal.  I just want to say for the record, it took me ONE HOUR to put together this report from my old thread on RC and then to submit all 4 reports through the MBI Dashboard.  I do type VERY fast though.  Basically, I'm simply suggesting that folks not be daunted, and the reality is that if you keep your journal threads from day one, or at least, start one when you ge that first spawn, and file your reports as you go along, it will be MUCH LESS tedious work.

    Yeah, it took me a while because I hadn't documented start to finish, hadn't planed on this program when I started.  I did keep pretty good records though, just had to go back and piece them together.
