Welcome aboard one and all. It is my intention to post something substantive to the game at least twice a week and then allow a few days for replies. I realize we all have lives. This is a published scenario and I will be sticking to the adventure as written since I've never run it before. If you know what it is (I did not use the published name) please do not spoil the fun for others.
As I indicated in the recruitment process, I'm not particularly fussy about what version of CoC you use to generated your character sheets as long as you have a sheet to help determine outcomes of encounters or research or whatever. That will be my next request for you -- to send me a character sheet using the character outlines you have provided so far.
Here are the Quick Start rules for Chaosium's Seventh Edition:

I'm also perfectly happy with the D20 version or the 5th edition.
Thanks for gaming with me. I hope this will be fun -- and horrible at the same time.
