The easiest way that I do it is to open up an extra window and open up the old thread. Then as you write in the reply window, there is an 'instant ubb code' for URL. click on that and drag the link from the other window. watch that it automatically puts in the 'http://' twice tho. hope that helps.
Sounds like you've been doing good lately, other than Sunday, which I think gets a lot of Americans down. T
