1. Click on the plus sign where it says 'Attachments and other options' below the posting box. Then click on 'Browse' and find your file. If you want the image to appear inside your post (rather than underneath it) click on 'Insert Attachment'.
If you add more than one attachment, make sure you click on (more attachments) and don't try to add it in the same place as the previous one.
NB Attachments are a benefit for subscribers as they can take up a lot of space space on the server - but anyone can use the following system, which doesn't!
If the images appear somewhere else on the internet rather than on your computer, click on the little picture icon (extreme right, second row above the smileys that are above the posting box) and put the address for the image in between the img tags.
2. Click on the green box that says 'Actions' at the top of the person's post, then choose 'Quote'. If you don't want to quote the entire post, dlete what you don't want - and make sure your own words are outside the 'quote tags' (this will make sense when you try quoting.
3. At the top of each page, on the right hand side in the blue bit, it says 'Unread Topics'. This will show you all the threads that you haven't read.
