I received the PM same day this thread was created as well, it was looking wired but it serve it purpose. I haven't visited my Account Related Settings page for a very long time so I didn't know I added that option when I created my account and the secret question wasn't that secret as I have disclosed it severally while participation in discussion on the forum. I don't blame myself as I wasn't as knowledgeable as I'm now back then when I created my account.
I took his advice and removed the secret question as I also saw the forum warning which was making the whole option look stupid. I didn't see his message as a hack attempt but it was wired. Why haven't theymo disabled that secret question option. Basically anybody closed could easily guess this so called secret question especially mine (which has been removed though)..
