Can I run the client on my server?
WhatPulse is all about user generated statistics. When you run the client on a server, the statistics that are capture by the client are not generated by you, the user, but by many other people using your server. This means that running the client on servers is not allowed.
There will be a functionality in the future where servers are excluded from the rankings, which is when servers will be supported. This is not yet the case.
