Just some advice, You highlight your words that you want to link to and then you insert your link. E.g. My Challenge:
http://www.pokecommunity.com/showthread.php?t=286059 becomes '
My Challenge' without the apostrophe's
Furthermore, if you want it to say something when you hover over it, insert"title = whatever you want to put here withput spaces and remember to put []'s and [/title] voila! The words 'My Challenge' are links btw. For the last example:
My Challenge
