Hello
I want to delete my account and all the messages and threads I created.
Thanks
You can't delete your account. But you can request it to theymos by sending him a pm with reason of you account deletion. If he accepts he might replace your post with anonymous users.
For the individual posts you can delete it by yourself that is easy and for the topics of of course you can't delete but you can edit. Edit each topic replace text with some garbage text or "x" something this and later moderators will delete the topic as well.
if you want to use a script then use this created by someone:
Since you cant delete your account here, and deleting posts manually one by one is a pain, i made a python script to automatically delete all posts that can be deleted, and to edit those which can only be edited (changes subject and message to "x")
