I'm sorry that your question wasn't fully answered. I think there might have been a bit of confusion since there wasn't actually a question in the body of your post, but just the title of the question itself.
It seems that you're interested in beginning to write content for your Joomla site, and James had provided some links for you to our various Joomla resources related to writing content. If you weren't attempting to write articles, what exactly are you trying to edit with your Joomla site? We would be glad to provide as much help as we can, but without specifics about what you're trying to do, we are just guessing at what you need help with.
When you're saying "how do I access my site for editing", as James had mentioned, for Joomla you would login to your Joomla administration panel
to begin editing the site.
I took a look at your account, and it seems like I see your Joomla /administrator/
directory, but I'm not seeing the core Joomla files just sitting in your main /public_html/
directory. Did you follow our guide on how to install Joomla
when installing this? It looks like you probably need to have Joomla correctly installed so that you can properly access it.
Please let us know if you have any further questions at all, and we would be glad to help you.
