OK, I think I'd like to sign up for Historica, and Mitgardia seems to suit my build style (and also the brick colors I have at home, to be honest...), so... do I need to go somewhere specific to "join"? I'm trying to get familiar with things but I'm a little lost, even though the relevant threads are all stickied. I am a complete newbie with this! Thanks in advance for your help :)
