You created a poll together with Spleak and now you want your friends to vote? You have to copy the text she returns into your friend's messaging window and send it. If your friend has Spleak, he or she can call that specific poll by copying the same text in the Spleak conversation window again and then answer to the poll's question.
The problem, however, is that you cannot (right-click and) copy the text in the Spleak window because a security issue involved. What you can do is:
1. Select the text.
2. Drag and drop it into your friend's messenger window.
Afterwards, type My polls to see the results of each of your polls.
This should work as a temporary workaround. We've been told Spleak will facilitate the exchange of polls in the future.
