I guess I should've expanded on this. I know of far too many situations where a crucial rec was never written because the writer "got busy" or --and this is quite common--the writer was too embarrassed to admit that she had no idea where to get the rec form or where to send it because she'd been out of the loop since graduating. (Or maybe she wasn't really a member of that group like that @#! relative of my husband's--I won't go there again.
)
Anyway, many PNMs are aware that recs may or may not be sent so I can see where they need the reassurance.
