Websense is a global leader in internet filtering and web security solutions to help companies productively use the internet. Unfortunately it had been blocking the ExcelCalcs site due it use of words like ‘Free software’ and ‘downloads’. I appealed to the Websense and I am pleased to report that they have removed the block. I imagine that many people working for large organisations have not been able to access the site because of this problem so if you have recommended the site to friends and colleagues please remind them to take another look by forwarding this email. Thanks.
Repository News
I would like to make a special thank you to Doug Jenkins for his kind contribution to the ExcelCalcs repository of solved problems. Doug Jenkins is a Civil Engineering consultant based in Sydney Australia (Interactive Design Services Pty Ltd). His experience spans some thirty years and he has been involved with prestigious projects around the world. Doug has developed some very powerful Excel functions. Doug appears to prefer development of functions rather than calculations on the spreadsheet itself. If you have never written any macros in Excel his calculations serve as excellent examples you can easily follow.
