I'm running firefox 3.6.13, and WebRep isn't working for me. I click the grey bars in my toolbar, and a)every site I've visited has all grey bars and no rep (even really large sites, such as the Oxford University Dictionary site), and b) if I try to vote, I can select categories and rate it, but clicking the vote button does absolutely nothing. I only installed WebRep a couple days ago & this is the first time I've tried to use it.
Also, the categories are VERY limiting. I wouldn't be able to rate many of the sites I visit because they don't fit into any of them. Luminarium is a literature anthology site, for example, and I also visit archaeology sites, mythology sites, and specialised encyclopaedias. They fit under none of the existing categories. I suggest adding an "education" category, a "science" category, and a "social sciences" category -- or at least, education. Most of the sites I visit either are informative but not news or contain literature or other fiction. I don't consider those "social/hobby," and certainly none of the other categories fit, either. If there's a forum for suggestions, I'll be happy to post this suggestion there.
