this really has nothing to do what what I'd like to know.. it's about the defiition of domain age in domain industry. which is # years it was renewed since last reg year, without a drop.
archive history and domain age are 2 different concepts.
keep this in mind in future. some people like me look speficially for aged domains. if I bought yorus withotu checking first, we'd just have a bunch of problems, cancelling transactions, reporting to mod for false advertising etc. at least in yoru case its clear you did not know.. some poeple like to plain lie abotu it.
have fun on np.
cheers
