Not a bad attempt at all, Mr. Rich. For the record, you got 12 right, 2 wrong, and passed on 6.

Which ones did I get wrong? Yahoo? I knew that one wasn't right. What was the other?

It seems I can only handle one guess at a time.

All DNAgal's guesses are so far correct :)

Oh duh. How did I miss eBay?

am I missing something, was there a link here earlier?

Sorry, I thought it was obvious - each letter is taken from the logo of a well-known web site. You have to name all the sites. No link, it's a YBNBY exclusive :)
