+1245 After some time, why does the botton at the top of a question("Post Answer") becomes locked after some time?
Yeah... 
Why's that? I don't know, but I am guessing that is because somebody answer it and it was long so after a while if no more people come to answer it, it locks it? AND maybe nobody come back and view the question...
And maybe because the one who anwer the question edited it, after I published this and edit it once again. I noticed it became locked!!
