How do I put my feedburner subscribtion widget into my wordpress blog?
You don't need to have any feedburner widget. You just need a text widget and create an image link point to your feedburner url and if you use self-hosted wordpress you can use feedburner plugin that will automatically redirect your feed url to feedburner url.
Go to feedburner.com (under publicize tab) for more details. You have to choose chicklet and copy the code into your text widget.
Hope this helps
