Something else I just noticed about the "landing page" (/forum-56/1-main-forum). Depending on how you arrive at that page (coming in "cold" from a bookmark or link Vs. coming back from one of the sub-forums) it may or may not have the menubar with the forum Search option. To be clear, by menubar I mean the bar with links to Recent Topic / Unread / New Topic / ...BlahBlahBlah... / Help / Search. Sometimes the menubar is there and sometimes it isn't, When it isn't the only Search available is the Nope! one. Pretty sure I don't need to explain why this is not a good thing!
Look into it later when the dust is clearing off the crater.
I have changed it now so that perhaps it is a little bit less crap. I have removed the site search from the forum, because that was where I always clicked, thinking that it should work. I also changed the "Limited" to be unlimited. There was a setting to limit the time range to one year, and I changed that now to "forever".
