User talk:2.27.20.66

I am being blocked from editing Wikipedia (and from setting up an account and logging in). I have in the past edited Wikipedia only very infrequently and uncontentiously - e.g. filling in additional information on my own entry. I wished to correct a small error on the page for Josef Popper-Lynkeus. I forgot, when I was trying to do so, that I was using a VPN, and so - understandably - was blocked. On trying it without the VPN, I found that there was a block - for several years - on my contributing, but that the reference given was to an IP number which was not mine. It is not clear what I can do: all help channels seem to require that I be logged in, which I am barred from doing.
