Hi. I am new to Mac, lifelong Windows user. So I am new to Macrumors too! I am having trouble posting ; ) I need a tutorial or help with basics on posting. For example, when I click reply to a post, it automatically copies the quote. If spend time thinking about what I want to say, it automatically posts without me clicking “Post Thread.” This has happened twice and I didn’t know how to delete the quote or cancel, so I posted nothing but the previous quote! Duh! I see the icons on the top of my post but once I start writing, how can I cancel or delete? Do you have a post outlining the basics of how to use the forums ? thank you! Donna
