Thought to give my feedback to this plugin:
First time when I migrated my site's content from bpm to rtMedia, there was some migration issues, so I reported on their support forum. And these guys helped out me very quickly. It was my mistake. :|
They mentioned before doing migration take backups and also deactivate all plugins and use basic theme, but I tried by neglecting their instructions and I got error.
But plugin support team help me to fix the migration issues and also fixed other problems which I was facing.
A big thanks for plugin developers and their support team. This plugin rocks.
Also found a good review on wpmu.org.
God bless to all.
Best regards and cheers,
