How do I use this site?

Okay so I recently created an account for this site, and I cannot find any Q&A or Help page on here. If someone could please help answer a few of my questions about navigating this site that would be amazing: 1. How do I look at questions I have posted? I see the "my active topics" page, but I believe it's only for another person's question I have answered. Is there anyway to manage the questions I have asked? 2. Can I delete a question/answer I have posted? 3. If I delete my account do all the questions/answers I have posted get terminated as well? 4. How can I search for questions by category? The search for similar questions was a bit confusing for me and maybe I really do need to just practice with it some more. 5. Is there a Q&A or any navigation help page for me to refer to? Thank you so much!

This is Richard's department (the owner). I would answer them myself but I'm very short of time today. Place your cursor over SUPPORT above (on the top Green banner under the People's Problems logo) and from the drop-down menu choose EMAIL (TECH SUPPORT), paste these and any further questions you have into the email and he'll get back to you asap.
