No need for dull detail, suffice to say that the hatlers hit a little difficulty this last week or so, and I PMed a member of yacf who I believed might have relevant experience that would help us out of our fix.
This is someone I have met, at most, six times, and on no occasion have we had anything much longer than a brief conversation.
Said member responded quickly to my PM with a 20 minute phone call, at the beginning of which they confirmed that they were able to help.
This has been followed up with a number of e-mails in which further advice was willingly and happily passed on, and culminated this evening with the expert eye being cast over a set of critical documents and the preparation of a letter.
I am incoherent with gratitude.
This is an extraordinary community we have here.
