The 'real' links to the checklists are still available if you click from the Character Profile page. These use the character's internal ID number, rather than the generated "XML Key".
http://cit.cohtitan.com/checklist/138 is an example. The rest of the checklists are provided at the top of the printable pages.
The javascript used to populate the checklist links is broken, as I appear to have omitted some double quotes in
/scripts/checklist.js.
Lines 14 & 15
$("#link_long").html('<a href="http://cit.cohtitan.com/checklist/long/' + keys[0] +'>http://cit.cohtitan.com/checklist/long/' + keys[0] +'</a>');
$("#link_short").html('<a href="http://cit.cohtitan.com/checklist/short/' + keys[0] +'>http://cit.cohtitan.com/checklist/short/' + keys[0] +'</a>');
should be
$("#link_long").html('<a href="http://cit.cohtitan.com/checklist/long/' + keys[0] +'">http://cit.cohtitan.com/checklist/long/' + keys[0] +'</a>');
$("#link_short").html('<a href="http://cit.cohtitan.com/checklist/short/' + keys[0] +'">http://cit.cohtitan.com/checklist/short/' + keys[0] +'</a>');
Side note on design:
You only have access to a character's printable checklists if they are marked as 'visible,' or if the character is one of yours and you are logged in.
For the XML, and JSON links, an 'xml key' was used because you are more likely to be pulling the information from something other than the browser. In order to somewhat preserve the visibility options set for the character, the XML key is only provided to the character's owner and shouldn't be displayed elsewhere on the site.
