As unity doesn't allow me to edit a review or the rating I've given for a specific product in the market, I'd like to state that I give a 5 star rating on all aspects to the 3col module by IlBelloDelWeb especially for the fact that its author was eager to listen to my problem reporting (which had to do with 3col's friend suggest feature and large user databases) and released an optimized version within 24 hours.
