Question

What is a tag anyway?  A demo tag? How do you put one or a group on a demo?

Answer 1

When you are adding demos to the site, there is a box of "tag" words.  I think you can choose up to 8.  Select as many as you can, since each word is searchable by the computer program that matches your profile to new jobs that come in.  It also searches the words in your description of the demo, so try to use words you didn't use in the "tags" section, so you get even more hits.
