The Server and you - What you need to know
Banned Items:
There are specific banned items for various reasons, make sure you read up on them here before you accidentally craft one you can't keep.
Rules
This is an important one, when in-game be sure to do /rules and take a moment to look them over. They are put there to insure you and your fellow players have an enjoyable experience while playing The 1.7.10 Pack on the XtremeIdiots server. The Staff do enforce them and rule breakers are dealt with accordingly. If you don't know something or understand something, ask. A good pointer to remember is if it's not naturally generated, don't touch it, whether it's claimed or not. This goes for peoples builds and areas that may have been inactive for some time.
Don't beg Admins for Items or Ranks.
No racism, or religious attacks. Anything falling under this subject will result in an immediate ban.
No griefing or taking from player graves that are not your own, this will result in an immediate ban.
No griefing or stealing from claimed or unclaimed bases.
No killing players without permission, this means that pvp will have to be welcome from both parties.
No sexist or anti-lbgt words. These could result in jail time or a ban from the server.
Do not attempt to bypass protections or people land claims.
No exploits, cheating or duping, this will result in a ban.
No AFK pools or machines allowed, this will result in jail time.
Be respectful - Have fun
Economy
You're probably curious as to how you will make money, and while this may seem intimidating it's not that difficult to understand. On the 1.7.10 Pack XI Server you can make money in 4 different ways.
/market (This option provides a global market to all users, you can buy and sell things for in-game currency)
/warp shops will take you to user created shops where each shop owner will sell a variety of items. To set up your own shop, speak with an admin.
/vote (By voting you will receive $250 and 2 diamonds; for a total of $1,000 and 8 diamonds a day, it basically helps you out with money, and helps the server get more activity.)
Player to player trading
Claim Blocks
By playing on the server you will build up game-time. Each hour amounts to 100 claim blocks that you can add your claim block fund. Using your claim blocks is fairly simple. Most of the time when you place down an item of significance for the first time, the claim block plugin will auto claim around that item but most of the time you will use a golden shovel. With your golden shovel in-hand, right click the ground where you would like to start your claim. Then in the opposite corner right click the ground again to finish your claim. A pretty decent instructional video can be found here.

Market
The server utilizes a global market plugin. Again, you can navigate to it by doing /market to see what's for sale, manage your listings, and to purchase items from other players.
