I have decided to switch our aggregator engine from planet to Gregarius. The new one does not support navigation bar. I am too lazy to edit the template yet. So, there will be no link from our planet (I still love the name planet) to our forums.
Our old planet can still be accessed at http://dae.linux.eng.chula.ac.th/planet/output/ while the new one is at http://isl2.cp.eng.chula.ac.th/~dae/gregarius. After some test drive, If no problem exists, I will switch our planet.cp-24.com to the new one.
