could any one tell me what 'linking' is please?

On your homepage there's a tab named 'Garden' where you can record what plants your grow. When you upload photos it's then possible to 'link' them to something listed on your garden page - where it says "Link photo to a plant in your garden?" From then on whenever anyone uploads a photo, asks a question or adds a reminder for that particular plant, there will be a listing under 'Activity on your plants' at the bottom of your homepage.

Thanks alot for that Bernieh, I have been wondering about that for quite a time!!

You're welcome Richardpeeej - glad to help.
