I created a new dotnetnuke site, and created a home.aspx page. I went to Admin->skins, and updated the skins with the one I just created, and parsed it. All seemed to be good, then I realized I don't see the "Admin" tab above the control panel, regardless whether I log in as host or admin. Can someone help? 

Thank you.

Yes, I still see the Host option in the control panel. I tried typing admin.aspx, it gave me an error. So I ended up adding a page named "Admin", and it sees to work, and I added the "Console" module to the new Admin page. The issue now is, the re-stored child pages under Admin are all empty, and I couldn't find many modules to rebuild those modules, such as Site Setting (uses Portals module), Security Roles (uses Users and Roles module). How do you rebuild those pages after accidentally deleted? If you have to take the new module definition approach, how do you create the new module definition? P.S. those modules are not the Recycle Bin.

Thank you for your help.
