Hello, flound.
I want to request two features at your pool.

1. User at port 7777 may select coins he want to jump at. It is good if you focused in 2-3 coins from the list and don't want to mine others. Coins from that list should be mined by profitability also.
For example, I don't want to mine LTC and FTC on port 7777 because as I see their profitability and mining time is very small. Hence, you can't even withdraw them.
You may select another port for such functionality.

2. Experemental coins port. Many users asking you about adding other coins to your list. You may select another port for mining them. Then you may watch on those pioneer-miners who mining at this new port and make a conclusion to add some of the coins to main list or not.
