May I ask us to update this verbiage on BayPIGgies.net. It is technically
completely accurate. However, the part of "Until then, please check the
mailing list and this website for updates" can be very confusing:

The reason I believe this can be confusing is that I am cross-posting this
again with this MeetUp site (how we used to do it -- it has much of the
same audience). I don't want to discourage those from signing up there --
especially as this is listed as sponsored by BayPIGgies and we link to your
Could say something similar to: "Until then, we are using one of our
member's MeetUp sites 'http://www.meetup.com/silicon-valley-python' to
promote BayPIGgies to new members. But, please always use the mailing list
and website for the official meeting information"

Machines take me by surprise with great frequency.
