@ravisharma – what’s your thoughts on this so far, how are you approaching it? I’d love to see some early concepts rather than just releasing the plugin outright. Who knows, someone might have some suggestions.

It’s not multisite, but my plan will be to use Multisite by the end of the year – any chance you could alter it?

Many Thanks,
Graham

Any luck with this Brajesh? if not ill remove that plugin for now.

Would you like me to cross reference all of my current ones to give you a rundown?

That way I’ll check what version I’m running at, along with your latest so you know what isn’t updating properly (and ill test and update them manually for now)

Can’t find the link haha – it’s just something I’ve used for a while. Here’s the PHP code (perhaps this is something you want to support.
