Cary Beuershausen is a Client/Server Programming Consultant in the Internet Solutions group at Alltel (http://www alltelmd.com) in Jacksonville, Florida. He has developed and implemented document management and workflow solutions in the education, legal, finance, and government sectors. His most recent work has been related to mortgage servicing and Electronic Bill Presentment and he's looking forward to providing B2B solutions in the mortgage industry with ASP, XML, and just about any other acronym he can find. Cary's tools of choice are Borland Delphi and Microsoft Visual Basic with a dose of SQL Server thrown in for good measure. In addition to being a full-time programmer, he has also found himself in the classroom teaching VBScript training classes that he developed. He has been pounding out code since his dad brought home a Timex Sinclair ZX-81 many, many years ago and he felt the rush of getting the computer to do what he told it to. Now he gets pumped up trying to figure out how to use the word "polymorphism" in every conversation. Robin Dewson started out on the Sinclair ZX80 (but failing to run a power station, as they claimed), then worked his way through the ZX81 and Spectrum to studying computers at the Scottish College of Textiles, where he was instilled with the belief that mainframes were the future. After many years, he eventually saw the error of his ways and started using Clipper, FoxPro, and Visual Basic. Robin is currently working on a trading system called "Kojak" in a large US investment bank in London, and it was here that he owes a massive debt to Annette Kelly, Daniel Tarbotton, and Andy "I don't really know, I've only been here a week" Sykes for giving him his "big break".
