tldarg is a Chrome extension developed by hardkornelius. It is a free add-on tool specifically designed for the Yammer platform. With tldarg, users can easily highlight their inputted text in red when their posts are too long and get truncated in the Yammer web UI.

It is important to note that tldarg is not officially supported by Yammer and there is a possibility that it may break in the future. The developer does not guarantee any fixes or updates for this extension.

If you frequently use Yammer and find yourself struggling with long posts getting truncated, tldarg can be a useful tool to ensure your text stands out. However, it is important to keep in mind the limitations and potential risks associated with using an unsupported extension.
