Teachers sharing one dot mac with iWeb need help- sites are being lost

Question

Sorry to be lengthy- Here's the question and issue first and then the background.
Question/Issue: Anyone know a way we can have multiple people (eventually 20 or so) with their own computers creating sites in iWeb and publishing them to a common dot mac account without wiping each other out?
Background:I am a teacher and at our school we have a single dot mac account. A few of us have been using iWeb (2 on iWeb 08 and 1 on iWeb 06) and posting our sites to dot mac with no problems. The iWeb 06 sites went to a folder under Web> Sites>iWeb in our dot-mac's iDisk; the iWeb 08 sites were directly under the Web>Sites folder. When sites were uploaded from different computers there was no problem (they all had unique names) and it worked great until this week.Even the 2 users both on iWeb 08 could send their sites to the iDisk and nothing would be deleted, just more site folders were added.
We are now all on iWeb 08 and so nothing goes into the folder on the dot-mac's iDisk under iWeb, they all go as unique sites- no problem I thought.
Our problem is now that when any one of us update our sites, it wipes out everyone else's site (since their site isn't on our computer). It didn't used to be that way 2 weeks ago !!! Could this be something new with the migration to mobile me (if it is, this really ***** for us)
I know a solution is to publish the sites to folders and then drag to the dot mac in sub-folders under Web>Sites instead of publish and each of us can have our own folder, but its a pain and not all of the teachers will be able to do this.
I think there is a feature in iWeb06 called personal domains, but I think we can only have 2, so not sure if this will help.
Does anyone know a way to set the defaults in the domain.sites2 file or in iWeb so it will use a sub-folder when loading up to dot mac? This way each of us can have our settings different and it will load for us automatically on the iDisk.
Does anyone know why this used to work and now it doesn't?
Any other ideas- Help Please

From my own experience.
When you publish to dotMac the index.html file in the root redirects to the top Site in the list of the iWeb domain file.
I use ca. 40 Sites in some 30 domain files. And most are customized after publishing. Plus a lot more irregular stuff.
iWeb remembers what Site in which domain was published last.
When I choose a different domain file, iWeb will create a new index.html file to redirect to the "new" Site.
As far as I could determine, none of the either published Sites are deleted. If iWeb did delete previous published Sites I would not change domain files.
In your case the following will happen. Every student publishes his/her Site(s). The last one published will be the default Site.
As long as no-one changes his/her Sitename or add a new Site at the top of the list, the default Site last published will be that.
Make sure everybody's Sitename is unique.
I use a custom index.html file in the root. So I have to pay attention that when I publish a new site, the custom index.html page is overwritten. I keep a copy of that index.html file in the root. I can replace the index.html file in case of emergency.
Does anyone know a way to set the defaults in the domain.sites2 file or in iWeb so it will use a sub-folder when loading up to dot mac? This way each of us can have our settings different and it will load for us automatically on the iDisk.
Don't look for hidden settings. If it was possible, it would be visible in the preferences. Accept the way iWeb/dotMac does its job. It wasn't designed to be used by multiple users with multiple computers and only one account. That should give you a hint.
All other problems are purely organizational. Personally I wouldn't trust multiple persons on one account. Give them their own account. If they mess up things they are responsible. Or find another solution.
