Test Shards Now Being Monitored for Inappropriate Behavior Oct 5 2006 10:18PM GMT (PST +08:00)
Due to a number of recent complaints of inappropriate behavior occurring on the test shard, our GM Team will now be taking petitions for certain offenses, including (but not limited to):

* Any name that violates the UO Naming Policy (link to the policy).
* Use of offensive or sexually explicit language, graphic descriptions or accounts of sexual acts.
* Organizing any guilds or groups that are based on, or espouses, any racist, sexist, anti-religious, anti-ethnic, anti-gay, or other hate-mongering philosophy.
* Using any unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, hateful, racially, ethnically or otherwise objectionable language toward any other player.
* Impersonating any Ultima Online Customer Support representative or other employee of Electronic Arts, past or present.
* Anything that violates any local, state, national or international law or regulation.

Any pages that fall outside of these categories will most likely be closed by a Game Master, as test shards will only have limited support.

We are committed to maintaining a safe and comfortable game environment for our players, so please report any of the above offenses on test shards by paging a GM.
