Is VPS working yet for resellers to offer it in their plans for clients.
Anyone??
Linux VPS is. Been for a while now 
how to use or resell it? 
you need to create vps plan through plan creation wizard.
Reseller control panel >> Info >> plan creation wizard >> Virtual Private Server plan wizard .
Any word of doing this for winvps resellers?
No way to even come close to this with windows VPS now.
