Being able to lock your own Requests.
The Graphics Request section usually builds up a lot of spam, even after the request was finished, people still post there, or post updated works of the work, that could have been simply, PMed to the user.
If you were able to lock your own request, after it was finished, things could get a lot cleaner in that section.
Just a suggestion.
Along with everyone else that posts this exact same post in the suggestions area which btw you really need to learn to search. The answer to this is no, want a reason here are some to list a few:
~ You could lock the thread because someone is flaming you even though they're right.
~ A thread is meant to invoke discussion, if you feel the need to lock your thread you obviously didn't put enough effort in.
~ That is what mods are for, understandably there aren't enough atm but still.
I think the difference between this request and others is that he's requesting it in a specific forum, which makes sense. The request sections aren't for discussion, and once the request is fulfilled, the topic is useless.
