Method 2 -- Working in your team's SOWE

You can set up Make Support in your SOWE and then build the targets of your project in it.
Advantage
It's generally faster than Method 1, since you have to update only one working environment (your team's SSWE).
Disadvantage (On Windows NT/95 only)
You must first check in your shared source files from the SSWE before opening the shared project in the SOWE. If you don't do this and later open the shared project in a PWE, the permissions for your Project Makefiles will be improperly set, and local builds in the PWE will fail.
Procedure
You can work in the SOWE just like you would in a PWE:

Check out your PDFs in the SOWE.
Set up Make Support and build the targets of your project in the SOWE.
If the build is successful, check in the modified PDFs. If the build is unsuccessful, correct any mistakes in your Make attributes and then rebuild the targets.
Update your team's SSWE. By updating the SSWE, your changes will be available to the rest of your team.
