While you can't import your reading list, if you have many titles on mangaupdates that you want to add, it might be a wise choice to make use of search extensions for your browser. https://www.howtogeek.com/114176/ho...lugins-add-any-search-engine-to-your-browser/ http://www.wikihow.com/Add-a-Custom-Search-Engine-to-Firefox's-Search-Bar-(Windows-Version) It should let you select > right-click > search straight on NU (if you add NU's search and temporarily select it as your main search engine). Or you can make use of addons such as "selected search" / "swift selection search" that'll let you choose from multiple engines at once. Definitely easier than "copy a title from MU > go to NU > paste and search" & repeat many times. Of course, this won't help you keep your reading status or anything, but finding series should be somewhat easier now.
