I wondered if you pay for say a gold membership, and then in the same order buy your all plugins package, do you get the 55% discount on the all plugins?   If not do you have to order the membership first, and then order the all plugins bundle to get the discount or does the discount not apply to it then.

Am I able to test themes before committing to them, you get 2 free themes with the gold membership, however you offer no way to preview the theme before using it.    I read this in another forum, how do I know if I'm going to like the theme if I have no way of previewing it first?  

Do your premium themes come with mobile support, your default included templates in your core version do not work properly on mobile.   For one they look awful on a phone with chrome mobile, and for 2 there is definitely a glitch I confirmed where once you reply to a topic you can't reply again unless you close the browser and re-open it.   This happened to 3 people with chrome mobile, 2 on a phone, 1 on a tablet, I'd assume if I use a premium template it's going to work right on smart phones and tablets.

Also Ultimate Member is an upcoming social profile plugin for wordpress, you should consider offering some form of integration with it at some point.  Buddypress just doesn't look professional enough for me and it never has.  People who have that and try to use simple-press have to find ways to disable your profile system and use the ultimate member profile system to apply changes to things like signatures, subscriptions, etc.  

One more thing, from what I see, your my credit plugin only adds hooks.   You should consider adding rank display and achievements for forum posts.  It can be accomplished with a few lines of code

mycred_get_users_rank( $spThisPostUser->ID, 'logo' )  gets the rank logo

this gets the rank badges

 $authors_badges = mycred_get_users_badges( $spThisPostUser->ID );

   if ( ! empty( $authors_badges ) ) {  
      foreach ( $authors_badges as $badge_id => $level )
         $tout.= '<img src="' . get_post_meta( $badge_id, 'main_image', true ) . '" width="50" class="mycred-badge earned" alt="' . get_the_title( $badge_id ) . '" title="' . get_the_title( $badge_id ) . '" />';
   }

echo $tout;

then it displays in your forum posts like it does here on the test:
