I´ve just send a post to the bumb module straight after it has been shared in a "auto-page-crawl" campaign.
The bumb tool has the following settings:
And this says the results:
So it seems that it does not care about the part: " Bump between 5am and 10am ".
It grabs the post and will bumb it exactly after 2880 minutes the post has been shared.
Of course I could calculate the minutes so it would start at 5 am, but I would like to know for what the : " Bumb between" Part is.
If you have no answer I will create a support tickets and see if they have an answer for me.
