I am suggesting some consistency in the lightboxes as some places have strong non faded edges ie the forum description and others have faded edges like the membership card. If i may suggest, i like the strong edges because that seems more consistent with the rest of the forum because i don't really notice things fading away.
I also like the strong edges because the bluebox that pops up also have nice strong edges, so the lightbox can be consistent with that.
Yeah, I suggest we keep it the way the upload file and forum description has it, with strong borders and change the membership card lightbox to have strong borders also. The strong borders keeps consistent with the bluebox ie the box that shows the list of followers and following on the member profile.
