Hello everyone!
Mike is absolutely right - publicly posting your license keys for X-Cart 5 packages and modules is a pretty bad idea since they are used to
activate the license.
That said, noone can steal the license from you using this key, but they still can use it to activate their own installation. And our licensing manager will come to you asking why you have two separate installations activated with one key.
So to avoid any misunderstanding, please, remove the license keys from your signature.
If any of X-Cart Classic(4.x) license owners is reading this, please, keep in mind that in your case license keys are mainly used for your and our reference. And they have nothing to do with the registration process.
And yes, X-Cart templates are essentially modules, so there will be updates for them too. So the customization rules for modules also apply to template packs.
