How to delete a post or change username

How do you delete a post and is it possible to change your username?

Underneath a post you have written there will be a series of symbols, a heart, a chain link, a flag, a reply arrow, and a pencil. Click on the pencil and you can get back to your post or your reply and edit it, or edit it severely by deleting it altogether. After a period of time the pencil, edit, delete function disappears, but I don’t know how long that is. I think it’s a matter of weeks or months, certainly not seconds.

There are ways to change your user name, I’ve seen it done, but I don’t know how to do it.

Yes, but you have to request it from an Administrator. You can do that with an email to but I can do it for you if you click on my name and contact me through a private Message.
