Please will someone tell me how I can copy some of the funny jokes that are put on the forum, as I would love to email some of them to my friends, without writing them all out

You can copy and paste. Hightlight the text, press ctrl+c to copy on your keyboard - open a word doc or email press ctrl+v to paste. hope this helps.

You can also just copy and paste the URL to an email and send the link for the person to open.

If you have a Macintosh, you can do as one already suggested.
Darken the area by dragging your courser over it, then go to the top of the screen to EDIT, then choose COPY, then you can push this page to one side and go to your email account. Open a page like you're emailing someone, then go back to EDIT and choose PASTE, it'll instantly be in that letter. You can go through it and delete or add to it, then SEND it.

It's real easy with a Mac.
