To post a link on BK for a link with in the site you type this
(note there is a . before each less then symbol and must be removed or you wont see the code)

<.a href="/Board?bc=535"> what ever your link is called<./a> this will show the computer board..
with internal links you cant use the entire h.ttp://brainking.com/games/ portion of the URL or it wont work..
External links to other sites YOU must use the full URL of the website.

Hope this helps
