Awesome Miner itself can be used with any mining pool.
To display correct profit information and use the profit switcher, Awesome Miner must know the current profitability of the pool, and not all pools and coins have integrated support for this. Learn more about supported sources for profit information.
Prohashing is very special as it uses the password field to specify algorithm information, and the Pool URL is always "prohashing.com:3333" no matter of what is being mined. Because of this special design of prohashing, it's not possible for any software to look at the Pool URL and see which coin or algorithm is being mined - all of them look identical. This is a major drawback in the design of prohashing and it will for that reason never be supported with profit information from Awesome Miner.
