Doodling sans pencil ......

This is my proof that I did try and set up a Doodle and embed it in my blog and was ready to send an invitation to nswpln@gmail.com. Maybe I will try again later .....
Doodle seemed to me to be a close relative of Google Docs when as an online group one worked out a mutually agreeable document whereas here the group works out a mutually agreeable set of meeting dates. It would be very useful in a large and/or dispersed organisation (e.g. multi-site library).
Google calendar looked very useful and I liked the way that you can have different calendars for different target audiences. Automatic reminders and offline access are a bonus.
I looked at Eventbrite etc. Anyvite seemed to be more directed to the private user and to offer assistance with designing your invitation with various pro formas although you could share your completed invitation and receive RSVPs, etc. Eventful and Eventbrite are more for the big event and more an announcement forum than for creation of invitations/notices. There are also clearer options for bookings and payments. Eventful seemed more used for arts-related events while Eventbrite was more general - even more commercial - in orientation. Eventbrite offered 198 events near Sydney, sorted by location, category and date (today/this week/this month). Eventful didn't show any Sydney events but there were a number from Melbourne.
Of the three Anyvite would be most useful to this library, but is unlikely to be used.
