hi John Redman,

Sorry for late reply to this,

Unfortunately that was not possible to edit from backend, but you can modify it from your phpmyadmin > under Easyblog subscription table

#__easyblog_blogger_subscription
#__easyblog_category_subscription
#__easyblog_post_subscription
#__easyblog_site_subscription
#__easyblog_team_subscription

Hope this help.
