Sorry Tibor. I'm still confused. I can't see either admin mode or user mode at the top of the page. Any more suggestions on what I might be doing wrong?
Make sure you are logged in.
click on Media Gallery on top of this page.
It now says: 'B AGGRESSiVE media gallery' on the top right of the page, in big letters.
Under that, aligned to the left is a bar with the following links:
'Home' 'FAQ' 'User mode' 'Upload File' 'Logout[Tibor]'
If you see 'admin mode' next to FAQ (and no 'user mode' link) click on admin mode to switch to admin mode

click continue and you are ready to procede with step 2)
