In case anyone decides to work on that topic: I would really love to see a light version of the Teamspeak widget, that is, without detailed information on clients.
The reason is that I have to deal with a very restrictive rented Teamspeak server where ServerQueries are limited to 10 per 3 seconds (no possibilty to add domains to the whitelist).
Two requests, one for clientlist and one for channellist, would be enough to create a basic viewer layout.
Also, caching the requests so that multiple concurrent page views don't trigger a server flood alert would be great.
I had a look at the widget from @pitaj, but unfortunately my programming skills are rather low😢.
I know a AdSense Plugin already exist (nodebb-plugin-google-adsense). But it is not compatible with 0.7.x and the developer does not update it. So if someone could make a new one or update the existing one - that would be nice.
