Portals vs Jump pages
The concept of a portal originated in the Polish and German Wikipedias. In early 2005, the portal concept was imported to the English Wikipedia and the first Wikiportals were established. Later that year, a special namespace (Portal:) was created for portals.
The idea of a portal is to help readers and/or editors navigate their way through general topic areas to more specific topic pages. In essence, portals are useful entry-points to Wikipedia content.
The Community portal (seen the navigation pane to the left, both here and at Wikipedia) is actually a Project: namespace page.
Unfortunately, Portals are currently not available in MediaWiki. And so, operating under the assumption that Portals may, or may not, be incorporated into future versions of MediaWiki, we will utilize the following articles as top-level jump pages and build them up to look and work like Portals:
Additional jump pages may be added in the future. Please discuss your ideas on the talk page.
