Hi again! You would have to have a webpage of sorts to post your material on, then you could insert a "hyperlink" into your messages. Or simply type the web address in the body of the message to the person you wish to send it to. Most of the time it will automatically convert it to a link (however below it did not for me). Geocities offers a small free web page you can develop yourself.
as it appears above (the web address) people can simply copy it by highlighting it -->right click --> "copy" and then pasting it into their browser and hit GO! that would be the easiest.
i dont know how basic you needed the description, so sorry if i went to primal with the clicking actions. This would be the easiest. You just have to have a registered account with geocities/yahoo. You don't have to regularly use the email account just check into it every once in awhile and keep it active.
hope this helps. they should give you a very user friendly program in the process to develop your own webpage.
