Read them. Follow them.
Yes, it's tempting to level up your character as quickly as you can. Especially of you are looking for a PrC or some special ability. However, this is a ROLEPLAY server. That means you should be spending most of your time ROLEPLAYING, not killing monsters for experience. Powergaming will get you nothing but ignored by the DMs. Is there no one one to RP with and you have nothing better to do than kill monsters? Not an excuse. You can still do other things and them post about it on the boards. Chances are, a DM will pick up on it and give you a cookie. Here's a good example: http://www.ysgardhala.org/viewtopic.php?t=2362
If you are seen powergaming in the same place repeatedly, expect to be chased out. If you continue, expect to be DP'd and looted.
Notice a monster drops a +3 item repeatedly, or a merchant giving away items for free, or a monster gives an unusually high amount of experience? Report it to the Hala Team account please. People who report these things are rewarded, usually by being allowed to keep what they find. If we find an exploit and find out you knew and didn't report it, expect to be vault jailed.
The death system is NOT to be used to delevel your character in order to change skills and feats. If you do happen to delevel, you need to relevel exactly as your character was before.
Grief Style Play
CvC should always be IC'ly justified. If you instigate CvC, and you think the other player (not the character) may not be having fun with the situation, perhaps you should stop. It's also strongly suggested you follow the Gentleman's agreement. http://www.ysgardhala.org/viewtopic.php?t=2757
If you need DM assistance, use the DM channel, make a forum post or PM, or hop on #Hala in IRC. Don't send DM's tells bothering them with DM stuff while they are playing their characters. When a DM is playing their character, they are trying to relax. Would you like your Boss calling you at home and talking about work while you are trying to play? Same principal.
Send PrC requests along with a character background to the Hala PrC Manager account. If you send it directly to a DM, it will get ignored.
If you want a PrC then it must be justified by good RP, and you must be in good standing with the team. Powergaming to get to a certain level where you can take a PrC is not a good idea.
Last but not least, ignorance of the rules is not an excuse. Follow these rules, and use common sense and the game will be fair and fun for everyone. Break them, and expect to get a warning, vault jailed, or in extreme cases, banned.
