Have you ever found yourself staring down a deadline and the one thing holding you back is that the logo provided for you to use in the layout is the size of a 72dpi postage stamp ripped right off the company web page? And they only want it the size of a billboard! Well, don't bother asking, if they knew where it was they would have given it to you already. Instead, turn to the trusty internet, search for the company name and anything saved as a pdf. Download and open the pdf in Illustrator. If you have been living right, the logo embedded in that pdf is a fully editable vector based file! And there you go.
