hey jackie,
you should give it a try. uploads are smooth. Livestream is enabled but i think as long you cant send superchats with HIVE tokens wont be used much.
In order to login you need an account ON @threespeak which you then link with your Hive account via Private key (one time interaction, you DONT have to link accounts every time you upload).
On 3Speak you can directly post TO communties. So this might give you more exposure or connection with other artitst.
Take care and hive on!
