Forum posting
The default content of Subject is usually 'Re: <the name of the 'parent' post>'. You can change it though.
There are several tips concerning careful reading, writing and asking you might consider worth following - you will find them on the left-hand side of the Message field.
When writing text in Moodle there are several formats you can choose to produce your text, depending on your expertise and the type of browser you are using. Please refer to Formatting text for further information.
Sharing images through forums
When an image is "attached" as a file to a forum message, it is immediately displayed full size after the message (i.e. no need to click on an attachment). This an excellent way of sharing images without having to go through the process of uploading them as files and linking them from within web pages.
