| 7 |
| 8 Cue cards are small on-page help items that appear when the user has |
| 9 done a certain action or is viewing a project that is in a certain |
| 10 state. The cue card give the user a suggestion of what he/she should |
| 11 do next. Cue cards can be dismissed to reduce visual clutter on the |
| 12 page once the user has learned the content of the suggestion. That |
| 13 preference is recorded in the User PB, and the same cue card will not |
| 14 be presented again to the same user. |
| 15 |
| 16 Exmple: The logged in user has dismissed the cue card that tells him/her how |
| 17 to search for numbers in the issue tracker: |
| 18 |
| 19 POST /hosting/cues.do |
| 20 cue_id=search_for_numbers&token=12344354534 |
