Ok, so tangents always seem to happen.
I was going to renew my account, and I noticed that I had two gift certs - one for $1 that I do recall getting, and one for $8 that I don't recall getting. I was wondering why I had gotten it, and recalled dimly a page that showed why. The usual site and faq search didn't show up anything, so I grabbed my copy of the SVN and started grepping, starting with /shop/...
Then it struck me - none of /shop/ is in the main SVN. A bunch of other pages aren't either...
Is this code lurking in some undisclosed module of SVN?
Does anybody else know of other code that isn't in SVN? (and I do recommend you check cvs/multicvs.conf before stating it here, /js/ almost caught me that way).
This was the closest I got to my final quest as to why I had the gift certs: /manage/payments/giftcerts.bml
