Limit Poll votes by userID and not IP
The Polls module on nanoHUB records the IP address of the user who took the poll and limits one vote from that IP. Can we record the user’s username/uidNumber instead and limit the poll to one vote per user (instead of IP).
I understand most online polls limit votes based on IPs to prevent automated scripts from spoofing the poll. Since nanoHUB polls require you to login, this should not be an issue.
This will also solve the problem where multiple users coming from the same IP cannot take the polls.
