Who is the mother? (1)

For 7 years now, Ted told his kids the story of how he met their mother but what are the known facts about the mother?,like do we know a name? Do the actors know something we don't?

First of all the basic facts about this series. There will be a 8th season but that doesn't mean it'll be the last. But some problems will occur.
-The kids are approximately 15-17 years old, so 2013 will be the year, where we at  least have to meet the mother
-Jason Segel aka "Marshall" just signed for the 8th season and said, he won't sign in for a 9th.

So every post of the series "Who is the mother?" I'll introduce about the mother.Each of them with a short comment and a rating.
1st: The Tracy-Theorie:
In the Episode "Belly full of Turkey" Ted goes to a strip-club and meets a girl called "Tracy", who is impressed, that Ted payed a lap-dance for a hobo. When she introduced herself, Future Ted says to his kids..."And this is the true Story of how i met your mother". When the kids are shocked, he reveals, that is was just a joke. But for a second the kids fall for that. So, some think that "Tracy" might be the actual name of the mother.
Rating: This theory seems very likely at the first look, because the kids know their mothers name. But the fact that Tracy called herself "Amber" first and later told Ted her true name, could have confused the kids. So actual it may be just the context and they didn't even have the time to say something like "my mothers name isn't Tracy"...Also the writers of the episode (Phil Lord & Chris Miller) never appeared again, they were only guest-writers. My conclusion:
Not very believable.

So if we don't have a plan, do the actors have some sort of idea? Check out this vid...

It won't be a nice first post if I wouldn't tell you, that actually some actors know the identity of the mother. Who and Why? There was always the problem that Lyndsey Fonseca and David Henrie are growing up. So in the middle of season 2 they shot a scene directly relating to the mother with only the Director, a cameraman and the two main authors being present, so actually they have had a plan since the first season...so lets hope they have found a good conclusion how it'll end.
