Yes, the server price to claim land is set to a certain amount. I believe it is now 1000 noobz, I could be mistaken though, I haven't looked for a while. If you want to let everyone and by everyone you mean the whole server, you would type /town set perm outsider/ally/resident switch on. I will double check this command, if you want to make sure it works, just type in each one separately, like /town set perm outsider switch on, /town set perm resident switch on etc.
