I found editing hubs is a problematic thing for several reasons.
(1) Initially when I write a hub and submit it for publication, it gets published immediately. But when I edit a hub, I find it taking a long time to get published. Sometimes around 3 days
(2) At times, whatever I do to comply to the suggestions of the system, it does not get published. There has been three occasions in which I had to finally abandon trying.
I would love to make small corrections to some silly mistakes I had done in some hubs. But with the present fate of things I am afraid to do so.
I am very new here and am not aware of the situations that was happening earlier. Correct me if I am wrong.
