Not really a clan, but still an organized group, so tags are not necessary, so I find Soviet's argument as a tad flawed. It's not likely that we would have loads of members, I mean, not that many people know how to make maps AND will be willing to join. This is for those who will be willing to help other members with projects within the tiny Cartographers community.
The {C} symbol is only to identify the clan and clan members. If it has o be changed to {BC}, then so be it.
