So a close friend of mine and I are intending on splitting the cost of a Dedicated Server. What I'd like to know is if there is anyway to set it up so that we each get billed half of what the cost of the server is per month, so that she can pay her half and I can pay mine. Basically 50/50 down the middle. If this is possible or if we can work something out similar to this I'd like to know. Thanks!
