I mean I know, how I can create new.
So if I create new account, and I dont wanna use this account. What will happen should I then say here when I start use other account, or is it just enough to stop posting with this account. Reason: namechange is hilarious.. and so on. My current name is very low reputation, because firstly new joindate + alot and alot question about how to use this site.

So Now i will start this page with new name.

This isn't allowed, you may however change your account name here: http://forums.d2jsp.org/settings.php?c=12

15. No multiple accounts - only one account per person is allowed. You may not under any conditions create more than one account per person.

I am sorry, but there is no "if" in this case.
You are simply not allowed.

A namechange is the only way and you have to put aside some forum gold for it.

Well, thats not the problem. Question is should I tell here when I start use that new account? to set TradeShop to Locked status?

If you do that and you make a new account, then that account will highest likely be locked as well

Do not make a multi account, both accounts will be disabled and any additional accounts you make thereafter will also be disabled.

You know the rules, please stop trolling in GH.
