Dear Craig, thank you for your reply.
Yes, I am logged as host, and I can see both the admin and the host tags.
Also, I had not set any start or end dates. Now I put 08.01.07 as start date and 08.01.08 as end date, but the problem persists. (the events I had added were in Aug 07, so they should appear)
I have the same problem with the "links" module.
When I go to these modules' menus I only get the options, "import content", "export content", "help", "online help", "print", "settings", "delete" and "move". There is no "add new event" option.
Help please!
Thank you
Gerardo
