There are over 300 third-party modules in CMS Made Simple, and this number grows weekly. Some modules do not work as expected, as there is no quality assurance for the third-party modules. However, sometimes you do not need to use a dedicated module to solve your requirements. With some creativity you can divert modules from its intended use to create your own functionality.
There is no sophisticated module for the service desk in CMS Made Simple. However, if you need it to handle support tickets, then you can use the module CGFeedback; which was originally created to handle comments for the pages or news articles. Although this module has not been developed to handle support tickets, it can be used to solve the required features with some advanced customization.
