I'm just getting familiar with a similar gig so don't have alot of recommendations, but alot of EM orgs are just opening up to new communications methods, from the Internet to SMS to social networks, blogs and twitter, yours shouldn't be too far off if they haven't accounted for these media yet. Don't worry, it takes someone familiar enough with technology to evaluate and make some recommendations, against some familiar criteria: is it secure (or in certain contexts does it have to be), is it survivable, and is it cost effective (not just in dollars, but does the new comm run on old equipment, ex. twitter or SMS over your existing blackberry devices)? FWIW it may be a generational thing but I can't see the benefit in twitter yet, but a local Red Cross organizer thinks its the bees knees for informing alot of folks quickly. I need to set up an account...

Good luck Martin, let us know how it goes.
