I would like to delete all my posts because some of the posts i published arent updated or the services i used to sell are not available .
It's easier to just lock the topics.
Just keep your history, it looks supsicious you want a reset anyway.
OP has created several duplicate topics in the past, spamming it on multiple boards.
To preserve it, I've
archived his entire post history all here 
i want to delete this thread
Click "Move Topic" at the bottom-left of this page, move it to Other > Archival.
This is the wrong board anyway.
