Hello Mo.

Thank you for your interest in our plugin.

1. Amelia doesn't actually have time/date settings in the plugin, so everything is being pulled directly from WordPress. You would need to change the format in WP settings, and Amelia would simply use that.

2. The best way of doing that at this moment would be to provide some discount coupons to those people. You can have one coupon which can be used only a certain amount of time (set by you), or create a number of one-time usage coupons, and provide them to the members.

3. Yes, of course. All manually entered strings would have to be manually translated, though, if you're not using a multi-language plugin, but everything else can be translated using either POEdit or Loco Translate.

4. Multiple time slots is not yet a feature, unfortunately, but it will be pretty soon. I cannot tell you when it will be implemented, but we have it in our "to-do" list.

If you have any further questions, or issues, please feel free to ask, and we'll gladly help.

Best regards.
