Carole, here is how I posted the following link, which is a link to your question. The result is in step 6. Note that I use Internet Explorer:
1. Go the Address line of your browser and click on it; the line will "colour" blue;
2. Click on Edit, then Copy;
3. Click on the Reply button of the post;
4. In the new window click on the URL button;
5. Right click and then click Paste in the URL line; the URL you have copied from the Address line (see step 1) will appear in the URL line.
6. Then key the word "link" (this is just an example; you can use whatever is more descriptive) in the second line marked Title, then
link then click on OK.
Try it in the Testing forum! Good luck!
