Giveaways:
----------

Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have
been kind enough to provide us with review copies of some of their
books, which we will continue to raffle off as giveaways at our
meetings. The publishers always ask that the persons receiving
the books provide a review and/or feedback about their books.

Unigroup would like to thank both companies for the support
provided by their User Group programs.

As always, all of the books will be available for review at the
start of the meeting.

Note: Our book supply is currently running low, and we need to
restock.

-------------------------------------------------------------------

Fee Schedule:
-------------

Unigroup is a Professional Technical Organization and User Group,
and its members pay a yearly membership fee. For Unigroup members,
there is usually no additional charges (ie. no meeting fees) during
their membership year. Non-members who wish to attend Unigroup
meetings are usually required to pay a "Single Meeting Fee".

Yearly Membership (includes all meetings): $ 50.00
Student Yearly Membership (with current! ID): $ 25.00
Non-Member Single Meeting Fee: $ 20.00
Non-Member Student Single Meeting (with! ID): $ 5.00

* Payment Methods: Cash, Check, American Express.
MasterCard, VISA, Discover (since 2013).

! Students: We are looking for proof that you are
currently enrolled in classes (rather than working
full-time), and as such, your Student ID should show
a CURRENT date. We have been presented Student IDs
containing NO dates whatsoever, and in the
current environment, perpetual/non-expiring access
to university facilities just does not feel right.
If your ID contains no date, please bring
additional proof of current enrollment. Thanks,

NOTE: Simply receiving Unigroup Email Announcements does
NOT indicate membership in Unigroup.

Members: Remember to bring your Unigroup membership card with
you to the meeting, to confirm your yearly renewal date!
