Yes - I'm trying to use the terms 'safe' and 'unsafe' to mean 'read-only'
and 'not read-only', respectively. 
That's the usage of 'safe' and 'unsafe' with respect to HTTP that I'm
familiar with.

For example, which (if any) of the following two FORMs is 'safe':

<form method='GET' action='../cgi-bin/nifty.cgi'>
 <input type='submit' value='go' />

<form method='POST' action='../cgi-bin/nifty.cgi'>
 <input type='submit' value='go' />
