Let me begin by saying I am still not convinced that the Taim-Demandred issue is settled. I read the other theories and they definitely make good points but they do not mention past information.
In Lord of Chaos it seemed so obvious Demandred was Taim. Think about the knowledge that he displayed in front of Rand.
Finally I think Jordan may have threw in that part about not recognizing Damer to trick his readers so he could surprise them later. Taim and Damer were hardly friends and it was over a pretty good distance. The last thing Demandred expected to see was an Asha'man in a circle with Aes Sedai.
All I am saying is reread Lord of Chaos and A Crown of Swords before making a definite decision. If Taim is not Demandred I think Jordan has a lot of explaining to do about how Taim survived so long and knows the things that he knows.
wotmania says: Anyone who has been here for a while knows I have never been a big fan of the whole Taimandred theory, so I was very happy with the events of Winter's Heart in that regard. You say that Jordan will have a lot of explaining to do about Taim if it is proven he is not Demandred, but I think he would have even more explaining to do if it turns out Taimandred is the truth and somehow Taimandred did not recognize Damer. Just because Damer and Taim might not have been great friends does not mean Taim (Taimandred) would not recognize one of the first Black Tower trainees. I would also be horridly disappointed in Jordan if he put in that scene simply to throw us off the Taimandred track. So, at least for me, I am hoping this particular theory is now dead and buried.
