Regarning plugin usage

Dear friend,

I request to answer -
(1) If I use it https://premium.wpmudev.org/project/e-newsletter/ ,how can it be integrated with https://premium.wpmudev.org/project/hustle/ ?

(2) While using hustle plugin , is there any need to use https://premium.wpmudev.org/project/the-pop-over-plugin/ ? I mean I am not sure its activity is built in the hustle plugin or not

Thanks
Monsur
