In this season of elections and the oft-repeated call for change, more than one candidate has issued a call to action to his or her constituents (or prospective constituents). In the spirit of civic participation, two of our columnists have a call to action for you. If the proverbial squeaky wheel gets the grease, then now's the time to make some noise. This month, Doug Findley and Gordon Aronson invite you to contact Primavera and provide feedback. What do you like about its systems? What would you like to see change? With the recent buy-out by Oracle, Primavera will undoubtedly experience some changes and adjustments. If you want your voice to be heard, now's the time to act. Don't know where to start? Then do it through our website. The WPL Publishing staff will attend the Primavera convention in Las Vegas in November. We plan to sit down with Primavera CEO and co-founder Joel Koppelman and ask him questions sent in by our readers. Leave your questions and comments - as technical or generic as you want them to be -- in the Comments box at the end of each article. We'll report back with his answers after the convention. If you prefer to send your questions privately, e-mail them to editor@wpl.net.
