(I guess this is the place to go for suggestion box.)
Delphi Forums has a feature to input archive thread Message ID#'s into an input box to easily find old posts. If you have their premium package, specific messages can be found, all the way back to their beginning.
I did not see one in your advanced search box area, unless I missed it.
Some of your threads I find thread ID #'s. Archive links referring to your previous board don't link. I can source a page to find the referring url. With an ID# and an input box, it should be an easy task to find old threads.
I read a lot in here, all the way back to the 1st week you guys started up here.
