is there a way to see a log where all updates and checkouts from a SVN repo are stored? I need to know which users are updating or checkouting the contents.
You might want to have a look at the following post at stackoverflow and adjust as needed:
You're probably referring to Examining History, where the
svn log command:
Shows you broad information: log messages with date and author information attached to revisions, and which paths changed in each revision.
The SVN server normally only logs updates, but it can be set to log checkouts.
