You will need to copy the portion that you would like to quote. Go to your posting screen and then click on the quote icon. If you hold your mouse pointer up to the icon without clicking the label you will see directions below as to how it will appear and you will know you are the right one. Click on that and you will see [*quote][*/quote] appear. (The astericks will not be there, they are used to disable the function so you can see it here)
Once you have the bracketed quotes you will need to paste the text you would like in between the two middle brackets. [*quote] Like This [*/quote]
You can also hightlight the text first and then click on the quote button.
Once you have finished with your post, click on the preview option and you will be able to see your quote box/s before you post.
Post when ready.
