I love the subject matter - I was touring Independence Hall in Philadelphia on New Year's Eve with my family (which is where this document was signed).  Following up with watching '1776' (the musical), and "National Treasure" in the following couple of days :)  So I've been having a lot of focus on the U.S. Declaration of Independence recently ;)   

Evgeny - if you can track non-registered users on the side, do they get included in the "View Count" for each article?  Or do only logged in readers get counted?

Another contributing factor in the underreporting of readers is the participants who read the articles via email.  I at least scan every article and question on the D.C. via my Inbox as I prefer an email-centric workflow.  However, I am counted as a 'reader' only on those articles and questions which I decide to comment on or answer.  I am sure I am not the only one consuming the D.C. content in this way.

@Jamshid Dehghanian  - You are running a Community Edition of InterSystems IRIS for Health, and the built-in license key will only work for approximately one year and then will expire ... this may lead to the message you're seeing.  Options include:

- Go to Evaluation.InterSystems.com and download the latest version of InterSystems IRIS for Health Community Edition

- Reach out to your account manager and ask for an extended Community Edition key that you can install on your instance

Note - your routines and classes will be stored within the Routine DB for your Namespace, so you should be able to look in the SMP and see which iris.dat this is and you can just make a copy of that file on the OS level (stop InterSystems IRIS first).  This will ensure that you don't lose anything for that namespace.  You can also back up your data database if that is important to you.  When you upgrade to a newer kit these should be preserved anyway, but I understand you'd like extra insurance so this is the way to ensure that.

Hope that helps
