[Radiant] RadiantCMS Mailer Extension

[1842759193]

Trying to install and configure the Mailer Extension into RadiantCMS ver
0.6.4, using the HOWTO located at

=> http://wiki.radiantcms.org/Extension_-_Mailer

cd radiant_app
cd vendor/extensions
sudo svn co
http://dev.radiantcms.org/svn/radiant/branches/mental/extensions/mailer

svn: PROPFIND request failed on
'/svn/radiant/branches/mental/extensions/mailer'
svn: PROPFIND of '/svn/radiant/branches/mental/extensions/mailer': 302 Found
(http://dev.radiantcms.org)

After some experiment, the correct URl seems to be

=> sudo svn co http://svn.radiantcms.org/radiant/trunk/extensions/mailer/

If this is incorrect, please advise.
