Thing 12

I am learning so much. I think I am slower than most because I get confused easily, but I can't believe all that I am learning.
To be able to locate an article again by 'sharing' is great. I print things out all the time and have stacks of pages...now I can just create a file of links and elimitate the print.
Can I put these links in a wiki?
This link is do a tree house story.

How long to stories and articles stay on a website?
Thank you very much.
