I saw that there have been some distressing conversations here about suicide. I've emailed Iwannabe ahero privately, but also wanted to check in here - I know how difficult it can be to see someone in pain and be stuck on the other side of a computer!
I'd like to give some general advice, which hopefully will help for the future.
Firstly, if you are seriously concerned about anyone online and think they are likely to hurt themselves, you should contact your local authorities (or, if you are under 18, talk to your parents or another responsible adult).
You may also want to suggest that the person calls the National Suicide Prevention Helpline on 1-800-273-TALK (8255). There's more about this phone line at http://www.suicidepreventionlifeline.org/GetHelp/Default.aspx . If they aren't in the USA, you can point them to the international directory at http://www.iasp.info/resources/Crisis_Centres/ .
It's better for the community not to create a big comment thread about a sucidal message or story - so you may want to delete it, or at least protect it (after giving the links above). And, of course, you can contact us at any time via Special:Contact if something is posted on the wiki that concerns you.
You also need to be careful to look after yourselves. If this is distressing you, you may want to consider protecting yourself by stepping away from the situation. You should also consider asking for help from family or friends offline. If you are under 18, please consider talking to your parents. The helplines above are also available for friends of those in crisis, so you can call them if you need to talk things through.
I won't be around a lot in the next few days, but I'll try to drop in to answer any questions
