I wanted to know how andy fitted the hinge pins on his artboxes, but I can;t figure out how to e-mail him as one member suggested and is there a way to ask question without it going to my home e-mail account any help would be appriecitaed because i really like the website, just having trouble figuring out all the blogs and forums, also it said i couldn’t post a question until i had 5 posts what is that about, thanks for any help.
