I think they mean another forum?
If you set up your own blog about depression you have to watch carefully for any idiots who might turn up - but as long as you set the comments to always be moderated for first time users - its not an issue.
The main thing is building up an audience - I've helped on lots of blogs and websites - installing them and learning the control panel - and making custom themes, avatars and so on.
WordPress is good - simple to set up and lots of free themes which make it look a certain way.
As for annoying people here- - don't be daft! Given the nature of the forum we expect people to vent here - indeed its better here than face to face with someone at times - as we often say things we do not mean - or have a desire to vent at someone or something but not upset people.
Nobody is upset by venting here.
If your looking for other forums - thousands exist but I'd say Suicide Forum is one of the top ten easily. I've perused though hundreds and hundreds of sites - more so for research as I never felt the need to join a forum up until recent times.
