Who should i contact to close a personal thread??

Thanks

They will not close it for you. You need to let the post die on its own. Just don't bump it or reply to it. Edit in CLOSED into your initial post if possible.

Alredy posted that thread is closed and people still replying and cant edit first post anymore, its very annoying

You probably have the post tracked and are getting notifications when people reply on the post right?

In that case you can go here: https://forums.d2jsp.org/tools.php and remove the thread from your tracked list.

thanks
