First Post!

This is definitely a first post.

JMacLabs.com has had a lot of first posts since it was first registered in 1995. Most of the content hasn’t followed it between iterations, and today none of the original content is left. The old sites were all static hand-typed html, then migrated to mostly html but with Perl CGI, photo galleries, etc. The first reference I see online is from 2002 and includes a link to the “old site (photos)” which includes stuff like this:
