The quickest and easiest way to renew your account is by doing it online here
Some areas of CGS are free-of-charge and do not require a username or password. These currently include a series of Drosophila example populations, as well as the "Create a Drosophila Population" tool that allows students to create their own Drosophila population to investigate by selecting mutant alleles from a physical chromosome map.
Instructors who wish to create custom populations for their students will need to renew their account periodically to keep it active. In order for CGS to be maintained and developed, a fee is required in order to renew an instructor account. This fee can be paid online via credit card, or by sending a check by mail. All online payments are handled through the secure Google Checkout system. The renewal fee is based on the number of students who use the software per semester for your course:
College, University, or High School Course |

Other arrangements can be considered if these options are not suitable for your course. Discounted rates are available if you choose to renew your account for more than one year at a time. If you have an account, you can log in using the link above.
