Use another plugin from another source

Can i add another plugin or addons from another source to install and use it in spicecrm?

SpiceCRM is a fourk of SugarCRM CE 6.5.22
We made many core modifications to improve the CRM and they might not be compatible with other plugins.
So try out. Make a backup before you install anything.
If you refer to TeamSecurity Plugin, this one shall work.
