Another 50-plus portal

This time the site is in New Zealand. Grownups.co.nz seems to follow the now well established format for 50-plus portal web sites:
Voting
Competition
Events by location
Games
Share a story/recipe/poem..
Forums
Medical advice
News & Weather
Classifieds

Compare the site to the UK’s best known (don’t confuse with well known) portal.

Personally, these sites leave me cold but clearly they appeal to a specific group of the 50-plus. How big and how commercially worthwhile this group is I have my doubts. Dick Stroud
