Checkouts uncontrolled??

[pad_123]

Hi all

I am new to CVS and CM but am responsible now for managing a small 
repository in my company.I have no one experienced in this field to 
ask these questions.
I have a question in general about configuration management.Is it 
necessary to document check outs from a CVS repository?Will it serve 
any purpose? will it make keeping track of releases,tags,branches etc 
more easy?is it a good practice to allow uncontrolled check ins to 
all developers in a project?If someone can advice on this ,I will be 
grateful.

Thanks,
Paddy
