Time and time again on Mn I have seen MN-ers rise to an occasion and help a poster in desparate need. Once someone's life was saved, and many times crisis has been averted and desparately needed practical and emotional support given.
Without wanting to pour cold water on the spirit of all this, can posters please bear in ind that even on first aid courses the firt thing you are told is check for your own safety before doing ANYTHING.
A few years ago close to where I live a man ran to a bus stop and begged women for help with his wife who had suddenly gone into labour and seemed to be delivering - a woman dashed into his flat with him to see what was going on and help, and was raped, almost strangled to death and then badly burned as he tried to set fire to cover his tracks.
In the past MN-ers have met up with posters who turned out to be trolls, with the intention of helping them with desparate situations.
I'm really really happy that PomBearEnvy's crisis was sorted out, and i would guess that she is a well known poster - but if there is a circumstance where the obvious way to help is to go to an unknown house in the middle of the night, then if the poster isn't known, people chould think twice, IMO.
But then, the man who could have helped Stephen Lawrence didn't cross the road because he had heard of youth mugging people by pretending to need help
.
We have to think the best of people, but there is already a novel which features a man who stalks his ex-wife by developing a persona on MN, and there are weird people out there who could see MN as a resource.
