The plugin is an awesome concept, and clearly a lot of work has gone into this.
There are two issues going on here though.
1) I'm getting the error "An error occured while submitting. Please reload the page and try again."
As far as I can see, there is no error.
This happens when I try searching, (and it still searches) and also while submitting a question (and the submission still goes through.) Which means everything is functioning fine, it is just throwing false alarms.
For now I have commented them out.
