Yes, the thread, you create is your decision. You can do what you want with your thread and can request Admin. or Mod.(s) to lock the thread for you if you feel like to but some ADers would feel that they waste their time to make their positive posts to help others with experiences, POV, education, etc when they know you would lock your thread without reasons (I mean no bash, etc) time to time. ?
Oh, so true... I don't think of that. Hey,

, don't worry. When I create my other thread, I'd better to not close it in future by then.
Welcome.
Yes, that's right.
I personally would not post anymore to any threads in the future when I know which creator who feel want their threads to lock without reasons because I don't want to waste my time to share my POV, experiences, education etc.
That's all what I have in my opinion.
Ah, I'm sorry if I waste your time... ... ... ...Especially, ADers. >_<
But, I get your point somehow.
