(I'd do the link but I'm not that clever).
Right click on the address bar of what you want to link to and Copy the address, then either right click in the reply you are writing and Paste it in the text here. This will put the whole long address linky thingy and looks a bit ugly.
Or, to make it neater, type a couple of words that describe what you are linking to, drag over them with the left mouse button held down and highlight them, then look for the little icon that's a blue planet with a bit of linked chain - it's underneath the white faced smilie. If you click this then a box opens up, delete the http bit that's already in the box and Paste the link into that and press Ok. It will now make the words you chose into the link and will show up in blue in your post.
Hope this helps. Give it a go with the pothole link.
