John is a sporadic poster who monitors AWAD in a desultory manner. Since his posts are interesting I hope this entreaty for more regular posts will not mortify him.
(off the top of my head)

Actually I would be more likely to use entreat as a verb than the above noun. Mortify is a stronger word than embarrass, closer to humiliate.
Not sure about peregrinate.
Any corrections from those who took longer to think??
