So I did. Spent a few hours after dinner for the past week, working on the googlegroup. Then experimented with Google Page Creator, and now there's a webpage to go with it. Sent invitations to a few people whom I think would be interested.
It's now ready to accept more people -- Non-Librarians, Librarians, Singaporeans, Non-Singaporeans etc. Sign-up here: http://groups.google.com/group/librarians-in-singapore
An informal networking group for librarians living & working in Singapore. But you DON'T have to be Singaporean or even a librarian. Join us if you're interested/ curious about "Libraries and Librarians".
