Finally did a painful switch over to drupal from wordpress. Most of it had to be done by hand in the end, but now I have the power of drupal at my disposal, bwah ha ha...
I want to develop some wiki content and needed a more flexible platform for it.

Sigh … waiting for linux to boot up. With 20:20 hindsight it was stupid to run linux as a virtual process in windows,  I’ve now got the most fragile linux distribution on the planet.

One of the main currencies for academics is citations. For better or worse, reputation, funding, jobs and promotions ride on publications and citations.
