It's not the crossposting she's annoyed about, it's that you're linking a completely separate chat site in the ad.
It's not only that I feel your trying to take users from TK and go "Use this chat and not TK" but that I was trying to save you from possibly being removed from the forums and chat by breaking something I thought was a rule, so in a sense I was trying to do YOU a favor. Go ahead and post your Rp here but do not link the other chat, do not advertise using that chat (If it is a rule, if not theres nothing I can do but say that it bothers me as a user of TK.) You can advertise your rp to your hearts content, cross posting is a very good way to get people to join, my only issue/concern was as Xach said, you were linking and advertising about another chat site, the equalivent of someone going room to room on TK posting a link and asking people to go there.
I also feel the need since you didn't quite understand my orignal post, to post this several times I had no qualms about you posting advertisments for your rp even if its on another chat, include a line asking people to PM you for location and time information and then link them the site via pms, cause then it doesn't seem like your trying to attract users away from TK. All in all the entirity of my post was written over something I recall other users catching some flak for in the past, so I tried to save you that trouble.
