Well the recent troubles posted here by a user is disturbing. You shouldn't do this in a public fourm, only as a last resort. First try it in private, in a calm and collective manner, asking for valid reasons. If no valid reasons are giving (ie. "Its for the RP!") Then make a post showing factual and valid reasons.
Personally I don't see a problem with a character trying to kill themselves. Hey, Abagail did it, why not others?
This brings to mind when that guy hawklen was banned. Man what an arse. He was a complete idiot on the way he went about it. What he should of done is pasted logs of the incident showing his side, and the team should post logs and facts showing their side.
Its idiots like hawklen and sol (forgot his name) that valid complaints and power abuses of the DM's are never taken seriously.
