missing comments

I found four comments from some months back, which I had not moderated, but have done this now, so apologies to Ralph, Derek and Jen...can anyone tell me how to add a list link of other blogs I frequently visit onto my blog? I have now discovered how to post pictures, add links in posts, and could eventually get the blogroll done, but if any one wants to give me a leg up on this process, email me at lawalleratbigponddotnetdotau or post a comment for me on this post.
Never too old to learn new things, but sometimes it is a case of 'can't see the trees'...
