Question
Website: ProjectManagementHacks.com.
Currently using the SumoMe plugin for sign-ups which is working moderately well and has the virtue of being free.
I'm willing to look at paid plugins (prefer one time fee to monthly recurring) if there is good data & case studies showing the value
Answer
Why don't you do a design hack rather than change. Add in the image of the actual report they get to get people excited. Also add it to your sidebar of the site and have your right side pop up show up further down.
