Seriously? In 2012 the topic “MDI” should be very short indeed: “Don’t do it!” not “Do it with delphi!”. MDI is a seriously old and broken part of the Win32 API and should not be used.
Other things not to start doing in 2012: Don’t use the BDE. Don’t start using BlackfishSQL because it’s no longer in Delphi versions past 2010, and don’t use anything marked “deprecated”, like TThread.Suspend/Resume.

You really have lots of good stuff here at about.com, Zarko – and I use this site often myself.
But you must avoid to recycle old, outdated articles by bringing them into your blog feed. This really creates a bad impression of what you really have here…
