To get this promoted you should add references to the to-be-continued thread.
Use [.msg] commands. (see dbCodes On (help) to the left when you are editing. In this case the x, y and z should be the f=, t= and msg numbers from the posts you want to refer too. See the http URL address in the address line of your browser when you are looking at the old thread to get those numbers.
Here is an example: use the peek button on the lower right to see how I did it:
[msg7,138,303]
You probably should but a -II on the end of the title to point out that it is a continuation thread too.
