This is a collection of random LOFAR-related links. You are welcome to add your own!
The LOFAR wiki is at http://www.lofar.org/ . Particularly important is the operations part at http://www.lofar.org/operations/doku.php .
The wiki of the User Software Group has much more information than just software. It also hosts the USG forum, which comprises a board about Long Baselines.
An important source for information are the LOFAR Status Meetings (LSM), or the newer ones.
George's google map of all stations can be found here.
This page should have up-to-date information about the status of all stations and general issues. The station rollout status table has less details, but now (hopefully) also information about the calibration tables.
current commissioning proposals
LOFAR control room smart board
ASTRON science support log has info about current activities
Some information about the issue tracker can be found here.
LOFAR software development pages with the doxygen documentation.
See here for more details, links to the presentations and additional material.
Unsorted documents from the tutorial at ASTRON on 12-14 July 2011 can also be found at http://www.astro.uni-bonn.de/~wucknitz/tutorial/
