Posting to second everything Kiht wrote, as well as to reword the following:
Sometimes, RP FCs can and will pull others into their plot(s) and/or interact extensively on a FC level with non-members and other FCs. That said, this shouldn't be an expectation, as it doesn't happen regularly or frequently enough with most free companies. We make the effort, but it doesn't always pan out, and ultimately FC and personal storylines of members take precedence before most non-FC narratives. Exceptions, of course, but that's the general rule of thumb.
EDIT:
Kayak quit making us blush.
