On the net, one can easily find a lot of specific websites each regarding a specific ongoing candidature to the WHL, which provide useful information about many aspects of the related site or even contain the complete nomination dossier often long time before it is actually evaluated by the AB. It would be nice to post here the website we would be able to find. I'll start myself:
