Abstract Submission
On line submission will be available January 1, 2000.

Abstracts from members:
ACA Members who have paid dues for 2000 should follow the instructions herein; no fee or deposit is required.

Abstracts from non-members
The Advance Registration Form and payment must accompany abstract submissions in any format from non-members. You may submit the abstract electronically and fax the registration form with payment information to (716) 852-4846.

Late abstracts
Abstracts with a postmark or e-mail date after March 1, 2000 will be considered LATE. Any abstract submission tagged "late" will be included in the program only if a $100 Late Abstract Fee is submitted. This rule will apply to ACA members, non-members, and invited and contributed abstracts. You may wish to fax your credit card information to (716) 852-4846 or e-mail it with your abstract. Acceptable forms of payment: VISA or MasterCard credit card, checks drawn on U.S. banks in U.S. funds, money orders or bank drafts drawn on U.S. banks in U.S. funds. No purchase orders. Abstracts received without the appropriate fee(s) will be returned to the submitting author and will not be processed until the fee is received.

Instructions for Preparation of Abstract
The entire abstract, including title, authors and their affiliations, footnotes, references, diagrams, tables, equations, etc., must fit into a rectangle 13 cm (5.1") wide by 17 cm (6.7") high and should contain no more than 40 single-spaced typed lines. Times font with 12 point size must be used. Abstracts not conforming to these dimensions will be returned to the author for revision and should be resubmitted before the deadline. Late fees will apply to these revisions.

Wording the title and first sentence of your abstract deserves a special effort. Make your main point there in the first sentence. Multiple parallel sessions and the large number of posters force meeting attendees to scan the Program and Abstract book selectively. Help them decide whether yours is a "must-see" presentation by stating your main point at the beginning of your abstract. The title should be in upper and lower case letters and should not contain more than 100 characters. Titles with more than 100 characters will truncated. A one-inch indentation must be left in the first line for insertion of the abstract number. The authors& names and institutions should be in upper and lower case.

Authors
The author named first in the abstract must present the paper. No one may be first author on more than one paper - invited or contributed.

Invited Abstracts
Abstracts for invited papers must be submitted in the same manner as those for contributed papers and are subject to the same abstract fees as stated above.

Abstract on the Web Site
Abstracts will be posted to the ACA web site before the meeting only if the presenting author's permission is given with the abstract submission. A list of titles and authors will appear on the web about one month after the abstract deadline. Each abstract will be assigned a temporary abstract number at this time. Presenting authors will be notified by postcard of their final abstract number, session name, and date, time and room assignment approximately 4 weeks prior to the meeting. This information will also be posted on the web site.

Submission
Do not send the abstract in more than one format. If you e-mail it, do not send a hard copy. If you send it via postal mail, do not e-mail it.

Revisions
The abstract processing office will not accept revisions. You will have to withdraw the original submission and submit a new one. The same abstract submission fee rules will apply.
