OK, thanks Jason. I have another question though.
Some of the folders and their contents within Power Messenger duplicate already existing folders, which are in the root, due to prior install of other WA products -- specifically, Power CMS Builder.
Would it be good practice to place only the top-level (root) files in Power Messenger into its own folder and place all PM folders in the root, and then adjust the paths from the files to the supporting files by adding "../"?
I'm thinking it would be undesirable to have duplicate folders and files, ie. both "/WA_DataAssist" and "/pmessenger/WA_DataAssist".
