I was afraid I'd have to say something to introduce myself. Then I discovered how to insert those userbox thingies, which saves me the trouble of actually saying anything substantive. I've learned recently to subst the userboxes, because some admins who are wound too tightly tend to delete them, sadly.

I am actually as fussy about English usage as one might infer from the list to the right. In fact, most of it is true and accurate to at least some extent. Except for the pillaging; I'm actually quite discriminate about my pillaging (Viking ancestry and all that).
