As discussed in Voting in polls directly by email. I’d like to be able to refer to a specific, existing poll by PM or in another post, and have the poll look and work the same. Simplest might be to have bbcode syntax e.g. [sharepoll topic=nnn name=foobar] where nnnn is the specified poll name. When the bbcode is used, the specific poll would be displayed. This would only be permitted for polls in public categories.
Happy to pay to have made a custom plugin or pull request to the official poll plugin. PM me if you’re interested.
