Hello:

It looks like you have two different accounts on our site.  Both of them should have access to the Community Support forums.  Silver licenses do not have access to other forums.

I agree that we should send the license code in the confirmation email - will add that to our list of things to do. 

We can't allow licenses on other domains though - our licensing server would require that we issue multiple sites with no way to control where they got installed.  Effectively, doing so would be a massive discount on pricing.  On testing sites you can always manually update the plugins - there's nothing that prevents you from using it on the test sites other than automatic updates being disabled.

When you install any plugin update the expectation is that the existing plugins are updated.  That's what the premium installer does.  Doing otherwise would be like installing an update when no update actually happens.

Thanks.
