How to combine multiple PDF files into one multiple page PDF

Do you have multiple single page PDF files that you'd like to convert into one larger multiple page PDF document? This is something that comes up a lot in the NMC, and here's how you do it:

1) Open the first page in Acrobat Professional

2) Document --> Insert pages

3) Select the next page to be inserted, and tell Acrobat where to put it (before/after the current page, at the beginning/end of the document, etc).

4) Repeat until all pages are added.

5) Save As for the new document.
