What I know about blog commenting is...
You should start with a hello
say who wrote the comment
Comment nicely
think about what you write before you write it and say bye
You can delete your comment if you don't want it to be up anymore
you can reply to someone's comment and you can report rude comments
last week we learnt how to put a link into a comment.
<a href="insert URL here">Insert display text here</a>\
Where it says Insert URL here, you delete and past the link.
Where it says insert display text here, you delete and write what you want to say e.g. " Click here to listen/watch/read"
Are you going to leave me a link comment? If so good job!:)
