We have several ways to participate in the Public Lab chatroom; the easiest is listed first, just below here. For other methods, scroll down!
Basic chatroom
Get started quick, no installations necessary! Open in new window: https://chat.publiclab.org
Public Lab's chatroom is run on IRC (on OFTC in the room #publiclab), but we host a web-based version to make it easy to get started. For more, scroll down!
To avoid being logged by the meeting bot (http://meeting.treehouse.su/publiclab/), type [nolog] before your message.
Riot.im
We also use the Riot.im service, which is a bit more fully-featured than IRC, also in the room #publiclab:
https://riot.im/app/#/room/#publiclab:matrix.org
It includes file upload, voice chat, and notifications. This is connected to the IRC channel as well, so it's basically all the same chatroom. Riot also offers several clients for iOS and Android devices: https://riot.im
Gitter
Some folks participating via GitHub use Gitter.im, and we've also bridged that with the other chatrooms:
