By 2010 I had been program chair 20 times, served on program committees of 100+ international conferences and on editorial boards of 7 journals. I believed I knew everything about running a conference and reviewing. I was wrong.
Modern EasyChair encompasses a much larger amount of knowledge based on the feedback from thousands of conferences and different communities. It is the system designed for its users, because the main designer is also one of its main users.
Andrei Voronkov (CEO of EasyChair, Professor at the University of Manchester and at TU Wien)

The system is great. Very intuitive, very powerful.
Kurt Mehlhorn (Vice President, Max-Planck Society)

Thanks as always for the great system. What would we do without it?!?
Manuel Hermenegildo (Director, IMDEA Software Institute)

After using EasyChair, one dreads the thought of running a workshop or conference any other way
Úlfar Erlingsson (Microsoft Research)

As you know, I consider EasyChair critical to the success of FLoC. It would be impossible to manage so many papers, programs, and proceedings without the support of EasyChair.
Moshe Vardi (Professor, Rice University and Editor in Chief, Communications of the ACM)

Hi Andrei,

I have been using your easychair system with great pleasure, for BPM05 and now for EEE/CEC06.... And I love it.
Fabio Casati (Professor, University of Trento)

EasyChair is a great system. Without it, I would not accept the invitation to be a program committee chair.
Tetsuo Ida (Professor, Tsukuba University)

MKM has been using EasyChair for several years, and we all agree it is the best thing since sliced bread.
Robert Miner (Vice President, Design Science Inc.)

I just submitted a paper to ICALP and was very impressed by EasyChair, which beats hands down many commercial packages I've used in the past...
Ion Mandoiu (Professor, University of Connecticut)

Terrific from beginning to end.
Pascal van Hentenryck (Research group leader, NICTA)

Dear Andrei,

We are organising MFPS in Birmingham next year and right now we are looking into different software packages to support the work of the PC. I remember that the one used for LICS last year (which was based at Manchester) was excellent, in fact the best I ever had to deal with. So far I have not been able to find out the name or the vendor of that package. Can you give me a pointer?

I'm very impressed by the paper assignment algorithm of your system - definitely the best result I ever got ... Both Thomas and I would like to use it for ICDT
Leonid Libkin (Professor, University of Edinburgh)

Dear Andrei,
...
I appreciated much PC-expert, that works better than the other systems I used so far as a PC member. Javier Esparza, who has a larger experience, is of the same opinion. I'll therefore propose PC-expert in other occasions that may come soon.

Dear Prof. Voronkov, I have been told by Frank Pfenning that you have developed a conference management system, that he consider the best he has used so far. Could you give me a link where I can get more info on EasyChair ...
