That is fairly easy. First open a new window for the page you want to include the link to.
Then on the address bar at the top, highlight the complete link The easiest way I do it is put the cursor at the beginning of "http://"
and then leave the cursor there and hold down either of the "Shift"
keys and the press the "End"
key at the same time and the address will be highlighted and with the mouse, "Right Click" while the line is highlighted and select "Copy"
Then go back to your post and type in, for example, "Click Here"
Then take the cursor and put it at the end of the e in "Here"
and holding down the regular/left mouse button, slide it over to the "C"
this will highlight the two words. Then if you look up at the top of the message window there are all kinds of symbols for Bold, Italic, Underscore and so on.
Then on the right there is But don't click on that, but two Icons to the left there is an icon that looks like a chain link. Click on that and a new window will open and http;// will already be there and highlighted, but just hit "backspace"
and it will disappear. Then put the mouse cursor at the beginning of the line in the box and then press the "Right" mouse button and select "Paste" and it will put the link that you want in there for you. Also there is an option for you to check to "Open in a new window"
For example, I am going to do a link for the main page of The Yule Log with the fireplace and stockings and you can click on it to see that what I typed in is not the full link in the message but will work click
As you can see the actual link is http://www.theyulelog.com/htmls/home.html
but I only used the word "click"
If you want to check that it works before you actually post the message, you can preview and if the link doesn't work, it means that somehow the whole link didn't get copied into the clipboard for you to paste.
I hope I am not making it sound complicated. It's second nature to me but now that I have tried to explain it, it looks complicated, but basically it is copy and pasting the full link you want
