No, it's not removed or anything. This is simply a note to you all.
Lately we've been seeing some instances where people edit their thread title to add a request thread closure (ex 1. "My SMW Hack. [Close Please!]). This is fine and allowed, but it's when a person deletes the original title of the thread to request closure (ex 2. "My SMW Hack. [Close Please!], where the struck out parts are deleted entirely) this is when we have a problem with it.
Therefore, we'd like to ask you users, please, if you're going to request closure on a thread of yours for any reason, do not remove the original thread title. Just add a little addendum to it. Thanks.
Try not to forget that the staff here do not bite (much). We are more than willing to close a thread for you if you send a PM to the appropriate moderator. It's probably better that you do send a PM than edit the thread title anyway.
I should like to add that replacing the content of the post with something like "please close." and so on shouldn't be done either. You can edit it in if you like, but please don't delete your original post.
That's exactly the reason. Imagine someone was searching for a certain thread in the forums, but everything he'd find was "SOLVED! CLOSE PLEASE!". It would be a pain in the ass to open each of those threads only to see what's in them.
