I am new to the macro world and need some help.

I am trying to set a macro that will place a comment. The information in the
comment should be:

User name. Datestamp (fixed to when macro was applied).

The comment should not be modifiable.

Is this possible?


(The object is to have this macro act as a "signature" for certain users
showing that they have "signed off" on information in specific cells.
Non-legal, intra-office use only.)

If there is an easier way than the macro suggestion above, I am open to
suggestions.

Thank you very much.
