 Overview
 
-   Right now, Tor user can manually exclude a node of all the part of
-   circuits created using the directive ExcludeNodes.  
-   This proposal makes this exclusion, less restrictive, allowing to 
-   exclude a node only on the exit part of a circuit.
+   Right now, Tor users can manually exclude a node from all positions
+   in their circuits created using the directive ExcludeNodes.
+   This proposal makes this exclusion less restrictive, allowing users to
+   exclude a node only from the exit part of a circuit.
 
 Motivation
 
-   Helping the integration into vidalia (tor exit branch)or other tools,
-   of features to exclude a country for exit without reducing 
-   circuits possibilities, an privacy.
-   This feature could help people from a country were many sites 
-   are blocked to exclude this country for browsing, giving them a 
-   more stable navigation.
-   Add the possibility for the user to exclude the current used exit
-   node.

+   exclude a currently used exit node.
+
 Implementation
 
    ExcludeExitNodes is similar to ExcludeNodes except it's only
    the exit node which is excluded for circuit build.
-   
+
    Tor doesn't warn if node from this list is not an exit node.
 
 Security implications:
 
-   Open also possibilities for a future user bad exit reporting.
\ No newline at end of file
+   Open also possibilities for a future user bad exit reporting
+
+Risks:
+
+   Use of this option can make users partitionable under certain attak
+   assumptions.  However, ExitNodes already creates this possibility,
+   so there isn't much increased risk in ExcludeExitNods.
+
+   We should still encourage people who exclude an exit node because
+   of bad behavior to report it instead of just adding it to their
+   ExcludeExit list.  It would be unfortunate if we didn't find out
+   about broken exits because of this option.  This issue can probably
+   be addressed sufficiently with documentation.
