Sami - whatever you like on this site, enjoy it. The original concept was that this site should be a free resource for those who needed it, and the site owner has made sure it has stayed that way.
That said, my favourite Full Members feature is their video gallery, a collection of hundreds (I should think) of videos - practical ones, informative ones, and sum just plain fun! I really suspect that you will enjoy them.
As has been said, this site needs Full Members to survive. It's got to be worth the small cost to keep it going, and even get better. Thanks for raing this, though Sami.
