Recently active topics in Spock tagged with missing spock features

Is it just me, or has a lot of the information / featuress previously available on Spock disappeared lately?

I'm referring specifically to:

* Spock Power
* Spock Leaderboard (the actual page still exists, but the link seems to have disappeared)
* Inviting trust (now seems to be replaced simply by 'Save')

* Most importantly - how does one send a message to other Spock users? This used to be a feature
