As I already mentioned in other threads, in my opinion it is essential (!) that GT focusses much more on interactivity.

In GT Links SQL the end users should be able to set up own categories and manage them on their own.

In GT Mail resp. GT List the end users should be able to set up own mailinglist lists and manage them on their own (like discussion lists).

In GT Community the end users should be able to set up own homepages and personal calenders and manage them on their own.

In GT Forum the end users should be able to set up own forums and manage them on their own.

In GT Autorespond the end users should be able to set up own autoresponders and manage them on their own.

Besides, a Yahoogroups or Yahooclubs script and a Blogger.com script should be developed.

Finally, it should be possible to buy all above mentioned products as a package and this package should run "out of the box".
