Will you sponsor this frog? The recording artist Neil Young famously sang “Sell Out” about other artists compromising their integrity to gain corporate sponsorship. We don’t want to sell our soul but we do need support from sponsors. We seek to develop our relationships with large organisations to which we can offer competitive sponsorship, software and training deals. Contact me to discuss.

ExcelCalcs serves a worldwide engineering community offering solutions to common problems and providing tools to make presentable calculation documents. Our reach is already substantial and our site traffic increases on average by 24% every single month since our start up in March 2007. In September 2008 we grew by an amazing 42% and in October 2008 our Google ranking increased from 4 to 5. We now have the same Google Ranking as other famous engineering sites like www.engineering.com and we are just one ranking behind long established engineering sites like www.efunda.com, www.eng-tips.com and www.engineersedge.com. 

Sponsors play a vital role in providing funds for continued development of the site. In return we can promote their organisation to a highly focussed engineering audience. Sponsors can share in our success and display banner adverts, advertise job vacancies and we even offer video advertisements

We need your help to procure new site sponsors and we offer free XLC Pro subscriptions to any users who bring sponsors to the site. Would your own organisation benefit from ExcelCalcs sponsorship? Find out, let us know and enjoy XLC Pro!

The number of calculations has dramatically increased over the past couple of weeks. In particular we are grateful to ExcelCalcs user infojunkie65 who has uploaded an impressive number of very fine calculations. A number of calculations provide solutions to wind related problems, frame analysis and spreadsheets which produce AutoCAD scripts. Infojunkie65 was one of the first registered members making many forum contributions in the past and I am delighted that he has uploaded some of his calculations.

Although he did not request it infojunkie65 is rewarded with a free annual XLC Pro subscription (normally $90USD). An XLC Pro subscription removes the “XLC Free Educational Use Only” and allows him to use the XLC program commercially. Please support us by purchasing an XLC Pro subscription for yourself.
