Well answer these questions for me and then descide.
1. Are you a Reseller?
2. Do you want users to give you false ratings?
3. Er... there is no 3 but makes me sound smarter if I include it! 🙂😛🙂
If the answer to the first two are NO then you don't need it.
If YES then have it.
Ratings are used by resellers, or people who don't really know what the Rating function is used for. This subject has been rasied many times here actually!
Anyway its not worth having the rating thing on! Adds more stress casue most people don't really know how to use it properly apart from people who use the Reseller forum, For Sale/Trade Forum.
Hope this helps!
Albert.
