It is a big job, and hopefully whoever gets elected will welcome the help. You can help out more than just with the big events though--if you want to post stuff up on Facebook, go ahead with it, if you want to talk to people about rides, go for it.
One of the problems with cycling club is that the majority of campus thinks we're in it to go fast and race bikes, and that we don't want to talk to anyone else. That's not true, and the more people we have out there letting people know, the less of a big deal going out for a ride will be. At the same time, we do want people to come to events, so there ends up being a fine line between us downplaying cycling (telling everyone they can do it, and that it's not a big deal, so come ride) and trying to sell it as something worth putting in extra effort to come out and do (doing alleycats, or going down to Fargo this weekend, or playing bike polo, or even joining the racing team and traveling to represent UND). Like I said before, the more people we have out there talking up the club (or the team, depending on your audience), the more people become okay with riding, and the more people we get in the club to help out with stuff.
Talking with different groups of people is why we have the message board, Facebook, and now the email list. Some people (myself included) don't do Facebook, so the message board is there to let them participate. Some people need to get all their information by email, and we're trying to accommodate that this year. Some people probably spend all their time on Twitter, in which case we should have a Twitter account. After all of this technology though, word of mouth still works the best at getting people to show up and ride, or show up and help, or show up and run for an officer position, so anything you can do in that vein would be most helpful.
