Our church would like me to take over the website.  I have made websites and have one myself but never worked with Wordpress and can't do anything with it.  I use HTML and CSS to create a web page and then upload it to my site.  The church site is run on Abundant with Wordpress and is completely foreign to me.  You can't FTP to it and you can't create a page of HTML and CSS, then upload it. 

In the process of looking for a work around I came across the plugin below.  Will it allow me to upload an HTML and CSS onto Abundant and be done, will it even do that?  Over the years we've purchased software that was supposed to do things for us and we've been disappointed each time.
