To contribute something of substance, my chapter was very technical (engineering school). We had our own website, servers, email listserv, shared google docs, etc.

However, when we visited a few other chapters they were universally amazed by our listserv. Many of them just had big mass email chains to do house business, or no email lists at all.

I imagine there are quite a few houses that have no such service internally but might be willing to pay for it externally.

The "fickle" comment mentioned earlier is legit though. Cabinet and house turnover can drastically change where the house budget is spent. That said, if you can lock down four years of service, it becomes "The Way Things Are Done", and it is usually very hard to change.

If you have some more questions (I'm a recent grad), my email is in my profile =)
