I am also working on multisite. I am curious if you have any tips on using user role editor and adminimize together on multisite. I have been using 4.5.1 for a long time now, and am using ure on a new site. Should I stick with 4.5.1 or will export config be ok to import to new current version, as I want to export my config and import it into the new site. Any thought s greatly appreciated!
