Hi
Thanks for interested in our extensions. Here are my answers to your questions :
1. can i use any social plugin with this? like for any document (free Or priced) user can share that on facebook or twitter (link of that document)
=> At the moment, the extension doesn't have social feature integrated. So it is not possible.
2. Is there any way user can control in which format he wants to download the specific document?
=> Unfortunately, it is not possible.
3. Is there any statistics available for users with most number of posted documents (i.e a plugin which shows top users list with highest document uploaded etc)
=> Sorry but there are no plugins like that in the extension.
What is the upgrade cost for this plug-in ?
=> You can use it for lifetime. However, for each purchase, we provide free upgrade for one year only. After one year, if you want to upgrade to next release of the extension, you will need to re-purchase.
5, Is there approval system for user uploaded files?
=> Yes, you can config the extension so that the files uploaded by users will only be showed if admin approved it.
Regards,
Ossolution Team
