Hi dlh,
I am sure it was not anything you said. You are more than welcome to ask questions.
I am sure you know, that you can view your dropbox directories and files on the web, when logged in. With the app from Arlen Beiler, you are able to open your wiki, edit and save it.
I used it yesterday setting up af new computer. With dropbox account limited to 3 devices, It did not install dropbox on this new computer. But I needed some of the information in one of my wikis.
Sure enough I got a mail asking if it was me logging in.
I think you should try it out yourself, just to get a feeling of how it works. Even if you normally work in another way it is nice to know your options, when needed.
