Hi,
I have not really posted on the forums much... but my friends said I should give it a shot and share the glitch application I just made.
It is called Glitch*BRGR! It looks at food for sale in the auction house and sorts it based on what food will provide the most energy for the lowest cost.
It currently is not very complex. It simply calculates the total amount of energy gained from all the units of food and then divides it by the cost of the auction. It then sorts everything based on the what has the lowest cost per energy point.
It is not perfect, but it is something that I only spent a day making. If people like it and seem to be using it I will probably make some improvements.
Have fun!
