If you look at the 2double site you should see a few changes.
When you enter a prediction there is a button to check the symbol and it will stop you entering a duplicate prediction. if you use the button and the symbol already has a prediction it will ask if you want to enter a vote for the existing prediction.
Also on the main table homepage there are three columns showing change over the last day, week and month. HOWEVER WE HAVE ONLY JUST STARTED LOGGING THE PRICE to calculate these columns so the week and month columns will not be correct in real terms. We are also awarding a gold, silver and bronze cup for each of the daily, weekly and monthly changes. we have the capability to award spoons to the bottom three as well but i am not sure what icon to use (it may be useful to see what has dropped the most because this may just indicate a buy opportunity so i don't want to be derogatory). Please note that the columns are not intra-day - they are to the previous close.
We are going to add a separate page which is the historical league table for gold, silver and bronze daily and weekly awards.
