How do I approve pending contacts from the spark client.
From the client, you simply add a contact, then they will receive a message asking them to allow, and you vice versa, BUT it is WAYYYYYY easier to just set the options from the server with the following…
in particular the “Subscription” plugin that " Automatically accepts or rejects subsription requests"
More info on this plugin here: http://www.igniterealtime.org/projects/openfire/plugins/subscription/readme.html
Hope that helps!
