A little quiet over the holiday period has allowed us to direct a few braincells to the multi-vote poll problem, and we now think that we have it fixed. Or at any rate it it worked on the test server and we can see check boxes rather than radio buttons in the sidebar.
So, the new poll gives a list of likely candidates for a Lifetime Achievement Hugo. You get to pick your five nominees. Obviously there are a lot more potential candidates. If you think we have missed someone important, please list them here in comments. However, we are going with the prevailing view that nominees have to be a) alive and b) have had at least 30 years in the field.
