After message is sent by attendee, system could send a response as received with a link to My response history page

We can do this right now! It is a feature that may be enabled or disabled for any given poll question.
You can use our Custom Reply Message feature to send a confirmation message that a response was successful (our default) OR customize the message to say whatever you want, including links!
This feature can be found by opening the poll configuration page > select Response Settings > and enter your Custom Reply Message.
You can see more details for how here: https://polleverywhere.uservoice.com/knowledgebase/articles/160732
