Combine 2 2010 PowerPoint Presentations

homeshortly made a comment on one of my  How to combine 2 or more Powerpoint Presentations: I thought it was important enough to share;

2010 is cryptic on merging two seperate 2010 presentations: 
There maybe another way, but this works pretty quick:

1) Open Presentation 1, click on last slide
2) HOME tab, NEW SLIDE drop down, chose SLIDES FROM OUTLINES. 
3) Drop Down file type, choose ALL FILES, then locate your other presentation
4) Press the INSERT button. 
Should place the 2nd presentation below the first.

Thanks
