Welcome to the #1\ annual 
Hudson River Undergraduate Mathematics Conference (HRUMC). 
Whether you are a student at your first
conference or an experienced speaker, we hope that you will find 
today beneficial, rewarding, and inspiring, 
and that you will make new friends.
Our aim is to build an atmosphere that includes
the message, ``We are glad that you are joining the mathematics community!''

This conference features fifteen minute talks by students and faculty, 
and a longer plenary address.
Each year, we invite students and faculty from  
universities and colleges in New York and New England to send abstracts
for the short talks. 
These describe research projects,
independent study projects, or any other independent work by students 
and faculty. 

If you are a first time attendee then
start by studying the short talks schedule to find some that 
grab your interest. 
Each of these is marked as Level~1 or Level~2: 
the Level~1 talks are accessible to everyone 
while Level~2 talks are aimed at faculty and advanced students. 

Note that each session has a Chair, who
keeps all presentations strictly to the schedule.
This means that you can easily move from room to room to see talks~--- 
you know that each talk that you attend will end on time, 
and each next one will start when it says it will.

If you are a first time presenter then we especially say, ``Welcome!''
Giving a presentation can be daunting, but is also energizing.
The session Chair will be able to help with any questions that you have, 
including any technology questions.

The first HRUMC was held at Siena College in 1994, and 
now it is an annual tradition.
For information about previous meetings, 
pictures from this year's
conference, as well as information about next year's conference
you can check out the web site:
\href{http://www.skidmore.edu/hrumc}{http://www.skidmore.edu/hrumc}.

Presenter or attendee,
we hope that you enjoy the HRUMC
and that you will you will learn a great deal.
And, if you can, we hope to see you again,
sharing your work, at next year's conference,  
hosted by #2.}
