Allow Demote to be changed to Promote

Idea created by graeme on Mar 7, 2011

    This idea has been merged with Ability to change my vote in ArcGIS Ideas.

    There is an ArcGIS Idea upon which I made the unwise to decision to Demote.  Since then I have discovered that I would far prefer to Promote that Idea because I've come to believe it is very important.  Can we have the option to change a Demote into a Promote, please?  If implemented please be sure that it turns a -1 into a +1 (and not just into a 0).
