Technically no, this is in the wrong session, as I intend to mount BTC as well.
Alright; so to answer your question, to 'create' a pool, you need to deploy some pool software on a server and get people to mine on it.
A quick browse in the
Mining/Pools board already brought up a very similar question by the way:
Costs for a Mining Pool Provider?[/url]
So this was about the costs, nevertheless BitMaxz already had linked the software you'd need over there. I also remember there are more similar questions popping up every now and then; as long as a thread isn't too old (necroposting), feel free to comment on one of those instead of opening a new thread with a question already answered elsewhere.
