I vote for no editing and no deleting. Rather make a time stamped post and correct the error that way. Need to clean up the past issues and get this site back to the way it was.
Charlie it’s an easy recipe and I believe that most trust you (and value your opinion) and think that just shows the honesty of the members. If a member is shown making corrections on a regular basis on won loss record, this will allow new members to not being manipulated. If it’s a -3.5 line and any of us mistakenly put +3.5 and immediately make a new post that says I made a mistake the line is -3.5. Good luck.
That would make you/me/anyone an honorable member amongst the whole forum. Also those that aren’t honorable in the tracing of actual records will be easy to monitor.
Just my 2 cents worth. Good luck.
