Those of us who have fat fingers and often hit the wrong or extra keys on our mobile devices would appreciate the ability to correct our typing mistakes.
I believe Telus took away the ability to edit posts as spammers were leaving clean messages and then coming back later to edit in the spam. Was quite prolific for a time before editing was blocked.
I wonder if there is a way that established users can be allowed to edit their posts within a certain number of minutes of posting them before they can no longer be edited? I'm not sure if that's an available feature of the forum software.
I agree with taking measures to reduce spamming.
I've been on sites where users had a short window (5 minutes) after the initial post to edit it. Other sites have a mininum post count before you were allowed to edit messages and post links.
Perhaps having 2 levels of users, verified and unverified would help. Verificatioin is done with a code sent to a Telus email address or Telus phone number. Only verified users can post links and pictures and edit their posts.
