>7285081 - I still remember it 20 years later.
There's no reason whatsoever that I should remember my ID. I haven't used the service in at least a decade, probably more. I'm often astonished at how the brain tucks away (apparently) useless information that comes to the surface via a chance stimulus. For me, such bits are sometimes many decades old and AFAIK unreferenced since being acquired. At these times I've thought to myself "there's absolutely zero reason this memory should still be in my head, it's insignificant and useless." I'd think the brain would have better uses for its limited storage, even for coldline data.
