i know there are lots of imposters around but is it possible to make an official list only clanleaders have access to, where we can add nicks of our members that are allowed to use a certain letter-combination (aka clantag

It is something like Authentication Extended

Not all servers support Auth, but if the master server could somehow transfer this information about clan tags it would work everywhere.
I don't know much about programming but I hope it is possible.
There are enough players who sometimes complain about "our members" which were never in our clan and I did never hear of...I think Ww, ID, Ct and all the others have the same problem and share this opinion. But I won't go so far to say "I speak for all" here
