Ok - here's the go (one more time, with feeling).
When you create a gallery, it puts it at the top of the list, and is called, by default, "untitled". However, when I look at the permissions of the album, I can see who created it.
When I am notified that you have created a new album (usually named "untitled"), or I see some new ones, I :
1. Edit the permissions to find out the owner and then give the owner (you!) full rights to the album, so you can add photos and create sub-albums.
2. Rename the album to your username
3. Edit the title to your username (this is the name you see in the galleries)
4. Sort them ALPHABETICALLY, by username
So...... when you see that your newly created album has gone, don't create another one - it will be deleted! Look for your name (alphabetically) in the albums!
There is NO point in using the rename command - that doesn't change the name that you see!
