Re : Polaris or Eta Carinae
- I'd use 1.8.2, considering 1.7.7 is the last version of Eta Carinae anyway and both have similar stability.
- moreneat is the most used theme. I'd expect it to be the best. It might not be stupid however, if you experience problems (particularly, Safari...), to add a bit of code in tiki-setup.php to determine the theme depending on the browser.
