A GroupShare installation can have a number of main TMs. For example, some installations have a TM for each subject matter area, and also a TM for each of their customers.
When you start a project, you can also create a project TM. This includes the TUs from the main TMs that have some match with the source texts.
When the TMs have different fields, the project TM uses only fields that occur in all the main TMs. This always includes the GroupShare-maintained fields.
To view or change which TMs are used in your project, edit the project settings. These specify:
Which language resource template, or TM template to use.
The TM sequences to use.
The penalties associated with each of the main TMs.
Which main TMs can be updated with new translations.
What confirmation levels are needed to update the project TM.
How TMs are used: the minimum values need for a match.
