1- do you have to have a feedburner.google account or can you use it as is with the ATA theme?

2- How do I add the 'as is' RSS feed to the right side bar...do I use BFA Subscribe under Widgets?

3- All I want is for my visitors to click on an RSS icon to subscribe to new / edited posts. I do not want the email or comment feeds.

Hope this makes sense. I did read through many of the posts already on the forum and never found exactly what I am looking for...a simple explanation..

3 - if you are talking about the icons in the header area go to ATO->RSS Settings and shut off the ones you don't want

I have already turned them off in the header...I want to put the rss feed icon in the right column as my #2 stated without all the other icons that come with BFA Subscribe.

this is another way to get what you want, maybe it's a simple way
just make a new widget, use TEXT widget
add this code to new text widget form

icon and feed address allready set up based on your blog and your feed address

Thanks...I will give that a try....simple is what I was looking for!
