bada_bing - It is because the score is based on
unique members. If the same member rates the person 100 times, their actual score only still increases by 1. It is more 'fair' this way and also prevents abuse somewhat. However in the 3.5.x version there is an admincp option to choose which style you want (i.e. unique or total).
Everyone else - I've been diligently coding away. I believe I have the vB editors working properly and parsing code correctly. I started adding some basic URL checking just to make sure they didn't enter garbage for the URL, but now it's turning into a full-blown thing making sure they enter in at least a correctly formed URL, that it matches up with the forum's hostname, then optionally you can have it check to make sure at least 1 of the 2 people created the thread in question, also you can limit validation to only certain forum sections (i.e. your FS/WTB only, so they can't enter just some random URL that they posted on your forum). Each various check can be set in the admincp options.
Right now I'm finishing up the URL checking, then I need to add in some code to return information when an error occurs for various things (so the user knows what they did wrong, rather than just a generic error message). Then I need finish up some editing ratings code & permission stuff, then it should be good to go. *crosses fingers*
It's close, real close... I'm getting exicted over this myself.

A lot will look famillar from the previous version, but there is also some new stuff (visually) and a LOT of new stuff (behind the scenes). One thing I really wanted to do with this version was ease administration and reduce abuse / false info.
Some things that won't make it into this version (but hopefully the next which I will release asap):
- Actual usergroup permissions for who can use the rating system (rather than just relying on the generic "canpostnew" and making it visible to that usergroup).
- Admin / Mod Utils for doing such things as IP checking, mass-pruning, etc. (However with the current system in place, a new person shouldn't be able to make unlmited ratings spamming your users like before).
- Other stuff I've forgotten...
edit - I would post screenies, but I would rather spend the time coding to get it finished at this point in time. It's not all that different from the last version.
