Since a Wikipedian in Scotland (right the far end of Britain from Leatherhead, the small Surrey market town where I live) was blocked from editing on a PC that supposedly had the same IP as I had been using when blocked (and, as far as I am aware, was from a different number series to the one that the few IPs I have had), I have been unblocked. i have decided that, with major exams coming up, i will only be an occasional Wikipedian and that the few edits I do make will be fairly major ones, mainly creating new articles.
