I saw you had looked at my profile so I thought I'd come and say hi....I've only been on the site for about a week so I haven't got many friends on here yet...I see youv'e also only been on here for a short time. Feel free to leave a comment or a message on my page anytime.....
Lookin at your page, I think you have got a bit confused with the commenting system...If you want to leave a comment for someone you have to go on to their page and leave it..you can't reply to their comment by leaving a comment on your own page. You need to click on their picture or their name above the comment they have left you, and that will take you to their page...scroll down when you are on their page and you will find their comment box...then leave a comment for them, try it on mine.
