None needed, I appreciate the help :) I should probably go back to the link and contact the project manager :)
Since I have you, I noticed you had posted about a year ago in search of some Tennessee wills. I thought I'd mention, in case you haven't discovered it since, that the Family Search site has some state/county records & indexes that I hadn't seen elsewhere. It has a lot of North Carolina probate records, for example. I did check on the Tennessee wills, and a brief check of the Will books in Overton County did not indicate any Arneys, alas. But I'll mention it nonetheless.
I always knew the LDS was a great resource for records in microfilm form, but had more or less forgotten about or didn't even know about their digitized records until recently. So in case you or anyone reading this had the same thoughts, you might want to check out the site again :)
