Can I send a copy of a page or article to a colleague?

 

Yes, you can. 
 
It is done through commands on your browser.  The process is sightly different for each Internet browser. You must always start with the page you want to send visible on your Internet browser.  
For Microsoft Internet Explorer,:
Click File
Click Send
This gives you 2 options.
  1. You can send a colleague an e-mail with a link to the page on your screen.
  2. You can send an e-mail with the contents of the page on your screen in the e-mail itself.
One advantage to number 1 is that your email is much shorter.  This means that you and your recipient each will require less storage space, and that your email will transmit more rapidly.  The is major advantage to number one is that your email is less likely to be blocked by organizational or institutional SPAM filters. The more material there is in your e-mail, the greater the likelihood of the SPAM detecting software confusing a part of your e-mail with one of the SPAM criteria that is in use..  Some organizations filter the mail immediately.  Others, put the longer e-mails aside and filter them when the server or the entire network is not very busy.  So if you use option 2, your e-mail might be delayed in transmission or it might be erroneously classified as SPAM to be sent to the Junk Mail storage and not delivered.
1 is safer. 2 is more convenient but more risky. 
Whichever you choose, an e-mail form will appear in Outlook or other mail program if you use it.  The web page contents or the link will already be in the e-mail.  You only have to enter your colleague's e-mail address and a subject.  Then send.  You may if you wish place your cursor in front of the web contents or link and type a paragraph of explanation.  As you type new lines that existing contents or links will automatically move down to make room for the new typed material.  
If you are using the Apple, Safari web browser,
 Click File
 Click Share
 Click E-mail this page
You will then be presented with the Apple mail form already containing the content of the web page.  You only have to enter your colleague's e-mail address, a subject, and then send.  You may if you wish place your cursor in front of the web contents or link and type a paragraph of explanation. As you type new lines the existing content or links will automatically move down to make room for the new typed material.
With Safari you do not have the direct option of mailing the link.  You may do this by:
Place you cursor in the address text box at the top of the Safari browser window.
Select the whole address
Click Command C.  This copies the URL to the clipboard
Open the Apple Mail Program
Click on the New Message button.
When the e-mail new message form appears, Place your cursor in the message box and
Click Command V.  This pastes the URL into the email
Enter your colleague's e-mail address, a subject, and then send.  You may if you wish place your cursor in front of the web contents or link and type a paragraph of explanation.  As you type new lines the existing content or links will automatically move down to make room for the new typed material.
The other web browsers all have a similar methods.
