CVS Annotate or FORCING users to comment their checkins

[S I]

Hi

Is there any way to force the users to comment or annotate their commits or 
checkins?

I know by default the -m "comment goes here" the system asks them to provide 
a brief comment, however, this can easily be bypassed.

Can a template be set up or is there anyway to do this through the Admin 
level?

Thanks

Steven
