There are two easy ways to add content to a blog - 'commenting' and 'posting'. The 'posts' are the date-ordered entries that make up the main content of the blog. The comments are shown below the posting, these are (ideally) about that particular post.
So if you want to extend the conversation around a post - add some extra information (e.g. a link), or offer some feedback, then commenting is a good way to do this. That way the comment stays with the post that it refers to, rather than getting added at the top of the blog as a new post.
Beneath each post there is a link to access the comments (e.g. '2 comments'). Click on this link to view the comments or to add your own comment. You can add a comment to this or other advice messages to let me know if this advice helps, or not.
GENERAL NOTE: Both the RCC blogs have been set up so that only 'blog members' can post or comment on the blogs. You have to sign in to post or comment.
