The yellow lock is an indication that a question has been "protected" by a Supervisor. Only Supervisors can then edit the question.
Protecting a question is a way to prevent a question from being repeatedly spammed or vandalized. If you want a question to be unprotected, send a message to any Supervisor.
(For more information, see the Related question.)
A lock means that the question is protected and can only be answered by a Supervisor. They are protected because they have been vandalised, or the question is ambiguous.
The reason why some Supervisors or CA's may lock your question is because it is prone to spam and vandalism.
"Preserving" a question is a tool only available to Community Assistants and other Answers.com staff. It is used to lock questions completely (so nobody can edit them, even Supervisors). It is mainly used when the Legal Department is looking into questions and needs to preserve them exactly as they were.
It appears there may be a typo in your question. "Phis lock" does not have a clear meaning in English. Could you please provide more context or clarify your question so I can assist you better?
The categories themselves cannot be changed, except by those authorized to change them. If a question is in a wrong category, contributors can recategorize them into the correct categories. Just click on "edit categories" under the question.
You get the key beside the lock then switch them.
of Lock
Only supervisors can 'lock' questions so the answer cannot be changed or edited. It's a tool that's usually implemented when a perfectly good or detailed answer is being vandalised by successive contributors.
When you find the first lock the next one will be beside the first
I think it has been proven.The Wiki Supervisor wins ... every time.Only a Wiki Supervisor could unlock this question and say it is NO CONTEST then lock it again.Let Chuck Norris try that!
Some answers are tampered with so they are locked to prevent this from happening.
This is not a question.
