Extedit_XH facilitates to have an arbitrary amount of so called "extedits", i.e. content areas, which can be edited by users logged in via Memberpages_XH or Register_XH. The plugin offers basically the same functionality as One Page for simpleMultiUser, but uses the editor of CMSimple_XH. For security reasons the file browser is replaced with a minimal image picker.
The plugin requires CMSimple_XH ≥ 1.6 and PHP ≥ 5.3.0. It is released under GPLv3.
