Not meaning to step on anyone's toes, but there is a slight flaw in this story: there was no World Wide Web until 1993, and most ordinary folks didn't start accessing the internet for personal/commercial use until the later half of the 1990s. This being the case, Star Trek could not have had much of a web-site (if any) while TNG was in production, and definitely not while Mr. Roddenberry was alive.
I know the website didn't exist when Roddenberry was alive, but when the official "Star Trek" site was launched, it did not contain any TAS references whatsoever (except for the Okuda "Yesteryear" and April bits) - not even TAS episode synopses - and then suddenly it underwent a major encyclopedic upgrade, marking the supposed shift in canonicity of TAS. I recall fans at the time being surprised that the original website had been treated like just another franchisee. (Previously, pre-Internet digital resources, such as Usenet and GEnie, were not Paramount-generated.)
