Ok, it turns out that the email that I referred to was sent about three months ago, not that they'd been in contact for three months.
Now it turns out that the charity have had virtually no contact for a few months. So, it looks as though I'm still involved in the website, and a meeting will be arranged in the next couple of weeks so that we can ascertain what needs to be done to update the site to bring it up to spec.
Damn, I hate jumping to the wrong conclusions. :o$
