In fact it's the kind of thing that cries out to be banged into the wiki, don't you think?
Unless you reckon that in six months from now it be easier for some random wanderer to find this thread on page 153 of the forum index, rather than the validation rules - user contributions page in the wiki? There's already a bunch of vaguely appropriate pages in there - perhaps you could sort through them, consolidate them where appropriate?
