Hi. Yes, it sucks when you want to help but you can't. I'm not a segger, but here are a few questions.
You say you have segged before. Was it here on Viki? I can't find your user profile on Viki.com under nikienana11 to check.
If you have segged on Viki, you must have worked with some CMs and moderators on various projects who can vouch for you that you do your job well even without a segging academy passed (for now). You could contact them and ask around for new projects.
If you haven't segged at Viki, that's a different story. Then people should really pass one of the two academies.
Another option is captioning, and not just in English for English-speaking shows. Some Korean dramas come form the broadcasting company with a transcript. Somebody has to punch that transcript into Korean language on Viki. Depending on your Korean language skills, this is something that's also an option.
Perhaps some of these fine folks can tell you something I don't know, or correct me if I'm wrong:
