Pixelmon Mod

My daughter has been playing pixelmon for a week or so, now when she tries to get on the server it says she is not white-listed, what does this mean please and how do I fix it?
cheers

same problem for me, have been playing on the pixelmonmod beta1 server for some days now. & today i can't login says i'm not whitelisted.

This is something you need to ask the server owners, not us.

how do i contact them? my daughter was also playing on beta1
