I'd never thought of doing it like that Grawrc! Learn summat new every day!
1) Basically at the top of your browser (internet page) you have a line which gives you the address of the internet site you are on, e.g. http//:www.allotments4all.co.uk -
2) if you click your mouse on it it will be highlighted in blue.
3) Then if you right click with your mouse on it (the address) you will get a pop up box which will give you some options, one of them is copy - select copy
4) Then in your reply on here when you are typing and want to add the link right click and a pop up box will give you the option of paste
this way it will take users directly to the page on the site you want ;D
