You mean it's not a official PDI Site? A few months ago this Site had content regarding PDI, i.e. construction works, drilling, blasting, energy and so on. I thought it would be the official Site, i wrote e-mails to PTQ regarding this Site correcting their typos, later on those typos were corrected. But now u got me thinking about it! I feel i got to write another e-mail. Ty!
