Physics Forums

@neilparker62 I will appreciate it, ...not yet gotten any reference... the reference am assuming will have letterhead physicsforums (an official one) ... other than that be blessed brother...

Hi again. I don't think there is anything like an "official" pf letterhead since it's just a website. But you can check with @Greg Bernhardt on that one.

@neilparker62 , mate, let me just go with what is there, i fully understand it if there is no official letterhead. Any letter will do. Cheers and thanks to reach out again...
