I am a highly visible member of the Embarcadero developer forums, which are public forums for software developers who use Borland/CodeGear/Embarcadero development tools (Delphi, C++Builder, RAD Studio, etc) to talk to each other, help each other out with problems in their projects and source code, and to provide expert advise to each other.
I am a contributing author to the C++Builder Developer's Journal and its support forums. BCBJ is a monthly online magazine devoted to all things related to the Borland/CodeGear/Embarcadero C++Builder development IDE and compiler.
