robtmelvin and Jack Jack both of you welcome to the build. You will find the official page for the GB in the Group Build Section of the Forum. The buid is called "Official Shiver Me Timbers Ship Group Build" And My name is Jeff Goodness.
So to answer both of your questions here we go.
robtmelvin: The LCVP sounds like its almost complete. Would be wicked cool to see some pictures if you have any. Your U.S.S. Laffy would be a worthy addition to the Group Build and i will add you to the roster with this entry. As far as rules goes their are no rules. Anything goes, add on's, PE parts and what ifs would be cool, any era goes. Yes the build started Nov 1st but like i said welcome aboard. Its open enrolment durring the entire build so people can come and go as they please!!!! So !!!! So as fare as preferences go, put up pics as you build or you can do them all the end, or just a finished product at the end of the build would be cool. So hope this answered your questions.
Jack Jack: again welcome aboard. Your U.S.S. San Francisco would be a welcome addition. So how you participate is by putting some pics up as you build and commenting on other peoples things as you see fit. some times people will have questions about refferences and stuff or will need help finding information about things and your welcomed to help. When you are 100% complete your build a Group Build Badge will be awarded. This badge then can be added to your profile, you might see other members of the forum with different badges. I am currently working on creating the badge and will have a couple for people to chose from shortly. Hope these answered your quesions.
