poll

The Advanced Poll module now supports approval voting in CVS. Approval voting is implemented by adding a "maximum choices" option for each poll. If it is set to one the poll behaves as usual and users can only vote for one option. If it is set to something else (something greater than one, or 0 for no limit) users may check off the choices that they approve of, up to whatever "maximum choices" is set to. For example, if maximum choices is set to "2" users may vote for their top two choices in a given poll.
