General search

seems like that is a big problem, many have faced this. try to get help in the Help section on the navigation bar.

How do I find customizers on this website? and become a fan?

Check where it says "Or Browse by Toy Series, Creator or Contest.", under the search fields.

When you visit a Customizer's Profile, there's a "Become a Fan" link there
Example: http://www.figurerealm.com/publicprofile?uid=55

(I would love to tailor the Showcase to customizers as well as make it easy for potential customers to find someone to hire, but it's not my call)

Nevermind. I see now, that it was moved and called "Custom search". Duh!!!

Heh, yeah. You can also still search by creator, series, etc, all on that same Search page.
