I want to share a url that links to a specific portal on the http://ingress.com/intel map. How can I do that?
I know no way to reference a portal directly.
However you can create a link like this http://www.ingress.com/intel?latE6=41380512&lngE6=2177417&z=19
Basically you have to find the coordinates of the portal you want to share and insert them into the link (you can use Google maps).
I hope either niantic labs or browser plugin developers will fix this in the coming future.
The "pguid" key in the query string can be set to the GUID for a particular portal in order to highlight it. Here is an example pointing to the Mosaic Sundial in Boulder:
But note that this seems to be a feature that only works (so far? :) for the IITC client
You can get this sort of link to a portal from IITC by clicking on the portal, and then clicking on the "portal link" link in the bottom left of the portal area:
