Pumping Station: One has an IRC channel on Freenode:
server: irc.freenode.net channel: #pumpingstationone
If you don't know how to or can't use an IRC client, you can use our web chat instead. You'll be chatting in no time.
The channel's useful for talking to members and parts of our outlying non-member community. If you have a problem or questions, voiced (people with a + symbol) users should be able to help you.

https://matrix.org is another chat technology. Its IRC integration is pretty nice, but #pumpingstationone is not quite one click away.
Of those options, Riot is popular. We use it to send cat pictures pretty often ;)
Once you sign yourself up for an account, then #pumpingstationone is one click away: https://riot.im/app/#/room/#freenode_#pumpingstationone:matrix.org
