This is the image I wanted to appear whenever a user got a 500 error message. The team didn't like it, though 
. Oh well. A different one will be used. Hopefully, you will never get to see it.
The Merrcury Engine (the software behind LetMeGo) is composed of several subsystems (see details). Three of these subsystems are known as the “communication subsystems”. They are in charge of all of the interactions we have with our customers. I recently blogged about the completion of the Morrison subsystem (email interactions) and the Cockerr subsystem (human interaction via tickets). Today, we are happy because the Web subsystem (the only one without a funny name) has reached beta stage, too. 
The Web subsystem is in charge of allowing our users to interact with our business via the web (obviously). Needless to say, this is how our customers will interact with us most of the time. The Web subsystem does not include any business logic (almost). However, it sits in the middle, between the user and the subsystems that handle the business logic.
The Web subsystem of Merrcury includes many neat features. Some of them are the following:
- A lot of AJAX, courtesy of jQuery, mostly.
- Whenever users see a date and time in our site, it will be render using the time zone of the computer.
- ACL-based permissions, courtesy of CakePHP.
- Friendly forms.
- Automatic browser check that displays alerts whenever the browser being used hasn’t been tested with the site.
- Every time a signed-in user gets a 500 error message, a ticket will be opened automatically, so that we can personally apologize for the issue.
- As with the Cockerr and Morrison subsystems, the Web subsystem is capable of full internationalization.
- And much more!
Pretty much every member of the team helped in the coding and QA of the Web subsystem (with the exception of myself, your dear author of these fine blog posts.) Thank you guys!
