Nice update!<p>If I touch "Edit", and make an update, then I have three buttons "Add item", "Submit" and "Cancel". I'm not sure if I should click on "Add item" or "Submit". (So I tried both.)<p>Also, after the submission, the item is not updated. I guess you (or some register users) must approve the change. It would be nice if the "thanks" message explain that, something like:<p>> <i>Thanks for your contribution! It will be reviewed soon by one of the Mathpendium members.</i><p>where "soon" and "members" are two fuzzy defined concepts.<p>It also should be nice to see how many pending corrections has each entry, to get some feedback that the correction was registered.
