Is Ethereum utilizing slack chat? (
https://slack.com/) If not, I think it should be considered, it can be integrated with IRC and provides some great features - their mobile app is particularly useful.
Several altcoins are communicating via this platform and it's a great way for the community to engage with developers.

There are no user limits that I'm aware of and costs are $8 per user. For 40 regular accounts, this would be about $320/mo, a relatively paltry cost for the communication benefits it could provide.
Because Slack provides an IRC bridge and free single-channel user accounts, it could actually make a lot of sense from a coordination perspective to start using it.
But with there great multi platform clients and easy integrations its a great way to get people active and informed
