I have installed this plugin and upon testing have noticed a couple of issues:
1. When adding an entry after submitting the suggestion the upload icon just spins for ages and nothing happens on the page, however the suggestion is submitted as a draft to the backend. From a end users point of view this has caused confusion as they not sure if they have submitted or not.
2. user votes are not being saved, when a vote is added the vote number updates but if they exit and then return the votes have not been saved.
