I think the OP is referring to internal links, especially to links to a comments thread or to links to the next post in a series -eg this one from a post entitled "vqc's Sit-n-Go Poker Moves & Plays" - http ://www.flopturnriver.com/phpBB2/viewtopic.php?t=30052

or from a post entitled, "Sit-n-Go Strategy Guide Part 1"
At the end of that one it says, "Click here to continue reading Part 2: SNG Strategy Guide - 6 Max SNG & Other SNG's.", but instead it is only the first 'SNG' that is highlighted in blue and the link leads to the entry for 'SNG' in your poker dictionary.

Also -note that I am forced to put space in the URL that I quote or else the board automatically uses the URL code and simultaneously tells me that I am not permitted to use it.
