Please feel free to drop me a line, I welcome your comments, suggestions and questions about any of my posts. However, if you have specific technical questions I suggest you try the forums at PLM World (free registration required). The breadth and depth of knowledge you will find there far exceeds the scope of my personal knowledge so you will be far more likely to get a useful response from there. PLM World is where I turn for help.
You can also ping me on twitter, @plmdojo.
