#MELPA has decided to no longer accept Lisp libraries from EmacsWiki. This includes my libraries, even though these libraries are read-only (administrator lock on the wiki pages). Too bad. This means that you must download Bookmark+ and my other libraries only from Emacs Wiki. Sorry about that. I upload Bookmark+ files only to the wiki.
