We had started our online presence at thinkanddone.com in Fall of 2007 with a collection of Visual Calculus Java applets. But with short on cash and hard pressed to pay bills we were cornered in to disposing our Visual Calculus tools at a fraction of it's actual worth. Now looking back at that financial transaction, I can see that the purchaser found his return on investment within 1 week of buying the tools from us. But that was long time ago and we are a forward looking company that now offers our web users the best and largest collection of investment appraisal software and guides. There are couple of sites that compete with us such as Forbes' investopedia.com and web encyclopedia called wikipedia.org. If you have visited our competitors' sites then you would surely know that our offerings are far superior to what others have to offer.

I work in a lonely place, as I am sole employee and owner of this web enterprise who takes all the risks and expects to collect the return on his investment. I only offer my web services to certain regions and if you happen to be reading this then you are one of the lucky people residing in a place where I am happy to conduct my business. I restrict access to virtually all of Asia only allowing visitors from Australia and New Zealand. In all of Africa, one can only access us if they are residing within Republic of South Africa. In Europe, access is offered only to residents of western and northern Europe. In Americas, residents of United States and Canada are permitted use of this site with rest of Latin America being restricted. This is all done not in the name of racism as some will cry and yell, but this is done to mitigate our losses that we have incurred in past by having our content been stolen and redistributed without our authorization. So it is all about my return on investment and has nothing to do with race, color, gender or country of origin.
