Actually, there is a way to learn your "number". On the Special Pages listing, under the "Users and Rights" section, there is a page called "Local list users". That page lists all the wiki's registered accounts, including those that are currently inactive or banned. The listing can be sorted by any of the column headings, one of which is the edit count. You are currently #69, although it doesn't look like the listing is updated in real time.

Because it's based on total edit count, the title "Top Authors" is something of a misnomer, as TAU's presence amply proves. A more accurate title would be, "Top Users" or "Most Active Users".
