Clan problems

[Eisenhorn]

I think part of the issue you're facing roach is that there isn't one group in the world called blackwatch, it's a fairly common name, and there is no way in hell of knowing if they are copying you or making their own clan.

Heck there's even a Scottish regiment called the Black Watch.

Hope that helps you, maybe they aren't copying your clan, maybe because it's a common 'cool' name for a group people will want to use it.
