Ok, I was digging thru some files of a vWii Nand dump that a friend has send me. However, I found that the file wc24recv.mbx was still existent under a vWii Nand. This is totally understandable, because some games, like Wii Sports, posts messages on your message board. If WC24 folder is totally wiped out, then the posting would be impossible. However, the posts are still in a form of email, sent and receieved by a same email@example.com Yes, that's an account for the vWii, which has actually abandoned WC24. Has anyone tested if that's still an acceptable Wii Number?
