We now have a chrome extension!
You can download the source from here
(That's from my fork of the repository, which is currently the most functional version, AFAIK.)
Here's how you can install it:
Download from the link above!
Go to chrome://extensions and check the checkbox in the top left labeled "developer mode".
Click the "Load unpacked extension..." button and navigate to the downloaded folder.
You are done!
To chat with other UniChatters, you can click the UniChat icon in the extensions bar!
Note: Be sure not to delete the folder downloaded, unless you want to break the extension.Huge thanks to LAX18 for creating the extension!
