Hi @kasino - welcome to the ReachOut forum!
Thanks for posting here about how to use the forum - hopefully I can help you out.
The forums are a place for you to talk about issues that are important to you, and receive support from other members if you're going through a hard time. They also exist for you to chat to other members, and offer them support if you'd like to 
You've probably noticed that there are a few different "folders" where people can post a new thread.
For example, there's the Tough Times section where people talk about difficult things they are going through, and others can respond with support or information.
Or the Wellbeing area where we talk about topics and issues. Every Monday night a discussion (called a Getting Real Session) is hosted on a specific issue -tonight, we're talking about grief
Or you can head to the Hang Out area for general chat.
If you want to read some specific information about how to post threads go here.
Does that help? Let me know if you have any specific questions or issues 
Looking forward to seeing you around the forums!!
