If you are not yet connected to the Talend Community, click Sign In to go to the Connect to Talend Community page to sign in using your Talend Community credentials or create a Talend Community account and then sign in.
If you are already connected to the Talend Community, your account is displayed and the Sign In button becomes Sign Out. To get disconnected from the Talend Community, click Sign Out.
By default, while you are connected to the Talend Community, whenever an update to an installed community extension is available, a dialog box appears to notify you about it. If you often check for community extension updates and you do not want that dialog box to appear again, clear the Notify me when updated extensions are available check box.
