A user profile describes an environment that the user uses to run the software for which issues are being tracked. The profile information include "Platform", "Operating System", "OS Version", and "Additional Description". Each user has access to profiles that they create (can be multiple), in addition to global ones that are shared created by other users. When reporting issues, users can elect to enter information like platform, operating system, version manually, or they can choose from the list of profiles that are already defined.
Global profiles are typically used by the administrator to define a set of standard profiles that are typically used by the MantisBT users. This makes it easier for the users to use such profiles without having to define create them. The access level required for users to be able to create global profiles is configured by the $g_manage_global_profile_threshold configuration option and it is defaulted to MANAGER.
