1. I will not update it, it's not really necessary. IPS has "See My Active" button on profiles.
2. I'm still thinking about it, because videobox also has comment & review system.
It's not necessary, the profile page has a tab "activity" to list the recent content items from all applications, and it also has a button "see my activity" to list a detail withdifferent sections for applications (eg: forums, videobox,...).
Try to go to acp and run "get support" to clear the badly cache. And make sure the review star and content are required, you can not submit with stars only or content only, both are required for a review.
The 2.0.x versions are compatible with ips 4.2. It does not have the feature to create videos automatically, you have to create videos manually.
Try to run "get support" to clear the badly cache. If it still doea not work, give me acp access I will take a look.
