I had three sites that I created with Frontpage that were hosted by AT&T. When AT&T got out of the hosting biz, and MS pulled the plug on FP, I started over with WP hosted by Hostgator. I have since added a 4th site. My sites are informational, personal blog, and a place to publish my Christian writing. I find WP very easy and very flexible - which is exactly what I wanted since I wanted to spend more time creating and less time “building”.
As others have suggested, if you built your pages with Frontpage, you should be able to handle WP easily. You will probably kick yourself for not changing sooner like I did.
Thank you
