Thanks for the link to the TBB comparison page, I forgot about that. Does anyone know who votes/supplies data each month? Is it TBB users or just random people who stumble upon that page?
If you go to the Main Site in the menu at the top of the forums, you will see these forums are in the menu on the left. In there is also the comparison link. And lots of other goodies.
The logins for the main site and the forums are separate, but you can use the same username and password if you wish and the username is available. I don't think you need to login to use the comparison link, but I just stay logged in permanently anyway, both there and here. Speedtests and such then get saved to your account - useful.
So the answer to your question is, anyone who finds the main site can vote

. Try it without a login and see. Logged in it stores your history, and you can also change your mind right up to the end of the month if you vote earlier. It doesn't count as two votes.
Note if you hover the cursor over a column you get the number of votes. You have to relate that to the number of customers each ISP has of course, and what you hear about them on the forums.
