I want a component for a joomla site that will work as a betting system. I want to be able to add tips, odds, and then after giving the results, i want it to calculate the tipster's stats (roi, total profit etc). i want tipsters to log in and add their tips alone. for each tips or articles i want to use a predifined custom template like it's showned in the attach file, but i'm listening to other received ideas . i am listening to offers :)
