JSFisher is the username for John Fisher, the adminstrator for this Holowiki site. His qualifications for having full authority over this compendium of all things holographic are minimal. In fact, he is the self-proclaimed World's Worst Holographer.
You may contact him via gmail. Remarkably, holographyforum was unclaimed as a username. The prior two sentences contain all the information needed for a human to send email to JSFisher; hopefully, spam bots will still be in the dark. Or, to be more obvious while still spam-bot resistant, holographyforum followed by an @ sign followed by gmail.com is a fine address for email.
