yes its gone a while back, it was great so no idea why, I still use it as i download all plugins on my own harddrive as I not trust most of the devs here to keep there stuff in order, here today gone tomorrow.

plugin should not be removed as den say before the dev leaves but the plugin stays so ppl that bought it can still download it if needed 

so why has it complete dissipated 

A purchase is a purchase. It shouldn't vanish if its taken away. :( 

I think this needs to be fixed. 
Keeping a record of your plug in key and a downloaded copy of the plug in is probably a good idea though in hindsight. =]

oxwall terms and conditions should state if a dev leaves there plugins go to oxwall 
who can then take the plugin up or pass it on to a dev that will keep the plugin going 

that's a fantastic idea! 

They could allocate a page for new or existing devs to pick them up and carry on the service.

Love it

makes perfect sense admin toolbox was a awesome plugin
