I have no intentions of drawing this out but it's patently obvious that to backup the wiki would require SFTP access to the files on the server, which is the access that was available only to a select few. I'm sure you understand this.
If you check the 2007 archives, you will see I was more than happy to setup a new site but it was very clear that people would view this as a "split" and so we agreed to make the best of what we had available. I then "did something" as you put it, which was a good chunk of the site that has just disappeared.
I think the many hours I put into the content that was on that site, gives me the right to say my piece. To suggest as you appear to be doing, that I may not have contributed enough to the development or management of the site is, may I say, a gross misrepresentation.
