I can't find the artist i've created

You mean that the Band Hyakkei , was added to equipboard ? I can not find it ? Can give me the Link to Hyakkei on equipboard ?

but when i try to add their gear to their artist page the finder doesn't show them. What should i do?

Ah sorry yes yes, sorry my fault , I did not read it correct.
When You add an Artist , this Artist get checked , an Artist has criteria to be added to equipboard.
So it did not get added , it was just an Request to Add the Artist, you have done, right ?
A real Mod will do this, so this will take time, it can take sometimes very long sorry,
because there are a lot of Artist Requests and added constantly like you can see on "Recently submitted artists" down on the Main Page.
But I think the Band will get added and has the criteria , they are famous enough, I like them too, hope to see them soon.

When it is not added in maxium 2 Weeks , ask me again please. There might be also a Web Error because of the Japanese Kanjis.
