In answer to your questions:
1. This is still not a feature of ClassiPress (admin can add to multiple categories, but users can't), and I haven't personally seen any instances where it has been customized this way. There are a lot of considerations to be made because of the fact the theme uses pricing per category options, but we are looking to implement this into the next Vantage release, so perhaps this may give some ideas as to how we could get this into ClassiPress in future.
2. The membership packs allow an unlimited number of ads, and the coupons are separate, so whilst you can offer a coupon code that can be used for a certain number of times per user, it's not technically tied in with the membership packs themselves.
3. As you can see from the
ClassiPress demo site, there are 3 tabs above the listings "Just Listed, Most Popular, & Random". Users can select from these.
4. You could make a modification to the theme to remove this information if you wish, however there is no setting within the admin dashboard to disable it.
5. This would require customization of the default theme on your part, but technically it could be done as there is no encryption which would prevent you from making such changes.
6. Again, this could be achieved through customization.
7. The new user email is configurable from the ClassiPress admin dashboard, but others would need to be modified within the theme files. Thanks.
