Great request. Thanks for submitting and commenting. Adding time-based context is definitely something we want to consider doing, so keep voting and sharing your ideas!
Terence - this is a great idea. I'm going to merge it with this idea: http://ideas.omniture.com/t5/Adobe-Idea-Exchange-for-Omniture/Trend-more-than-5-Key-Metric s-in-SiteCatalyst-15/idi-p/5003 since they seem like the same thing. That will allow us to track it better. Thanks for submitting it!
Done! And the best part is that I made this change in the code myself. Users now see a link to the "Reset My Password" page in the message that they receive when their account has become locked.
