Given how these forums handle URL's, I would suggest you Ctrl+click on the above URL's so that they open in a new window and are not cut off by the dimensions of this forum.
I am also working on a plugin for the AcyMailing newsletter component that allows you to email results and upcoming fixtures to all your subscribers. I am hoping to have this available by the end of November.
Please note, these are ONLY for Joomleague 2.x
