DL, You start the new thread as normal, click the URL button in the Intant UBB code array (it is right under the text box for posts and replies, upper left corner of the array.) Paste the url from the thread you wish to link to, (open the thread in a window, right click anyhwhere in the window, selsect properties, and then copy all of the url info from the window that pops up, (middle of the window).) After you paste the URL, fill in the page title(whatever you want to call it) It is pretty straight forward.

Thanks for the kind words.
