Other then that bad notify key error, there is one more issue.
When you supply topic link, while giving someone reputation, it doesn't work as intended.
Example:
1. Giving someone reputation.
2. +1 and put link in form.
3. Hit Enter.
4. User get reputation.
5. When you click on the reputation, it should take you to right topic link but it redirects to wrong link. http://fearless-assassins.com/forum/index.php?showtopic=0
Also, I have FURL enabled. Why it's using simple URL structure then?
