Question Edit time stamp

[SoTheySay]

Sorry if this has already been addressed -- I only recently got back on this account. I distinctly remember though before on threads/posts you could go back and edit them whenever, without the whole "Last edited: date and time" set up. I was just curious if this maybe became a necessity with coding perhaps?? Or if there's any chance this could potentially be removed again. It's a silly little "request", I know haha. Just thought it couldn't hurt to ask now that I'm active again on this account.

Thank you!
