Hi Clare,
I just wanted to jump in and say welcome to the online network. I hope you are finding your way around the site a little bit better??? There are some areas of the site which we know are a little confusing (we're working with our developers to see how we can improve this) but for now you might find the best place to start is the site's Help page and Q&A page. The Help page will also give you the link to the All Posts page as well.
Feel free to call me any time and I would be happy to answer any questions you have.
