DoznEggs: MB! I thought that might be the case, but I could have sworn I saw someone add a post to a thread wilst in that status. I guess I was mistaken?
People hide their profiles all the time here. They jump back and forth for whatever reason they have.I do think there is a 24 hour waiting period after you hide your profile to get back on the forums.
The thread creator may have written the thread yesterday, hid their profile, and came back today to answer the posts on the thread.
