So I've just joined the morag tong.
I do the first mission and take out the guy in the elven nations place. The prob is that no one else in the club will talk to me even after I present the writ to the guards. Is there any way to get around this or is it something you have to accept?

that's not a problem. they are not important anyway.

imho i wouldnt even bother with the morag tong cause all they do is give you hit jobs which some are outright dangerous. and there is nothing really to gain from the guild.
