Fiona,
The technical implications seem reasonable to me, but since I've never run a forum others would be able to support/debunk the reason given better.
But quoting someone's PM isn't generally polite. Maybe if you removed it and just paraphrased the technical reason given instead? It's up to you but I wouldn't want you to be rude without intending it.

And this forum will be weakened by your absence.
