I voted on those already, but a few comments:
2. Send a /msg to each new user with the link.
I'm not saying that we should (most likely
we should not, at least not without
approval) but this
could be implemented without changes to the server, by someone having a program that
monitors the "New users" section of
Newest Nodes and automatically /msg's them. Of course, it would be much better if the message came from
root.
3. Add a link to here to the new user's home node +/- an option to remove this link.
This could be implemented without the need for one more user option. Simply add it as the default text of a new user's home node, and then the user can remove it him/herself.
On the other hand, I upvoted this idea, but now I'm not so sure I like it very much, because all the people who create accounts and never come back will have home nodes with these little messages...
So here's another idea: how about adding a link to this node as the first thing in the "information" nodelete (call it "Welcome message" or something like that), and by default make it the first node, so that new users will be more likely to see it. Maybe make that link bold for all initiates.
