Well, the series doesn't necessarily need to have a story arc right off the bat. I think it would be best for the wiki to decide before starting the series whether or not to include a story arc and, if so, work out the details from there.

It's entirely possible for a series to have episodes that are independent from each other with no underlying plot arc (that's how they mostly did it in the "old days", after all). Like I said, it would have to be a community decision.
