25 man raid frame.

[DethsHead]

Ok, this may be my slowly waning vision,you can feel free to even call me a noob. However, when we were filling our 25man Naxx the other night we had 24 people, however the allotted frames were filled. the raid leader didnt use Nui+ so when I told him we were filled he sorta laughed at me. any help here would be grand. I hope you guys get a good laugh at this if its something stupid on my end.
