[Gluster-users] Add single server

[Joe Julian]

I am just a user, one that's been here for ten years. I've been highly involved in the community and spend countless hours if my own time contributing by helping users on irc.

I'm not a C developer and so I do not contribute code.

My point is that suggesting something is very different from contributing an idea. The most common user suggestion is probably the one about how Gluster should be faster about replicating across high latency connections, with no understanding of the speed of light or how to ensure consistency.

I have gotten to know many of the developers over the years. They would be happy to discuss possible solutions and once adequately formed, implement them. You should help. There is plenty that you can contribute if you would be willing to put in some time.
