This mod will allow guests to write reviews. If a user is not logged in, they will get 2 input boxes (for first and last name) when writing a review. If they are logged in, the name is filled in for them. I reccomend using the "review approval" system with this mod.
It's been so long since I've changed my OSC install to do this, that I cannot remember if there were any language files or any other files I changed for this. I think what is included is the only file I changed, but if you find an error, please let me know ASAP.
