In re: First Land, and new residents selling cheap
How about an automatic "Congratulations!" message when someone purchases first land, saying something along the lines of: You'll find that your investment can multiply many times in the near future. Many sims see a rise in value of first land of 6 times or more in the first two months! Your first land plot is not only land, but a nest egg for the future.
Or something. I only thought of this just now when reading the previous FL post, so forgive the lack of polish on the message.
In re: Griefers
How about a tool on the land tools that lets land owners set an "insta-ban" for anyone using push (that is what causes orbiting, isn't it?), and IMing the land owner. Except the land owner and their objects, of course. Many cool toys like Abranimation's Avitar Cannon and the diving board work by push. I've had to turn the "push" back on in my land so my toys would work for my guest, which is why I thought of this. Maybe except the land owning group too?
Obviously, some friends will ban themselves showing off cool toys, but I would imagine most would find it a "doh!" moment rather than a reason to be angry. I can envision a good number of emails saying, "dude, I just banned myself from your house, let me back in!". Also, some noob baiting, "Here dude, try this gun!" hehe....
But that ability would have saved me much trouble at Abranimation's Devil Moon when I got griefed two nights in a row...I and unsuspecting new residents were getting orbited and probably thought their client had crashed.
And yes, I filed reports!
