rabbitoid: As a slow player myself (but one who never tries to purposely hold up anyone or any one tournament - or take more then my allowed vacation days a year) - I think the idea of a graph to show how often a player moves would be an interesting idea - IF AND ONLY IF - it was optional, and a person can turn off their graph if they don't want to show it.
On the flip side - people should then be able to create games & tournaments in which they can choose to have a certain "speed rating" - and of course the users who choose not to turn their on will not be allowed to play those - but they can still play any regular game or tournament.
Honestly - I think it would be a lot of programing work on Fencers part... in which I would rather have him working on new games, but I can see how some sort of "speed meter" could be made & used... again, as an optional part of the site.
