Today I found a cool Frontpage 2003 feature to create Sharepoint weblogs within a few clicks.
What you should do is open Frontpage 2003. At the file menu choose 'new' select a Sharepoint team site in the task pane. At the packages tab choose the Web log package. Provide the url and click ok. Select all the option you want and click Import. Within a few seconds, the weblog will be created on the server.
Could it be any simpler? :)
