How do I delete my community profile ?

Holy Forking Shorts Microsoft!! I have for the past two hours been trying to figure out how to:
1.) Post on a forum! I read that it says go to the forum and there will be a button to post a question to a forum...none seen on my side

2.) I have inadvertently created a 2nd freaking profile ("JarrellCo") so I could see a thread I had originally posted under my main profile ("courtsheagraham").

3.) I want to freaking delete "JarrellCo" profile.

Please forkin help!! And for the love of little baby Jesus...make it freaking easier to find make a post on a forum!!!!!

I doubt I ever see this post again due to the complicated arse process it has become to make a post and find a previous post!! Who decided this was a functional way to do this!

PLEASE FORKING HELP!!!
