A: Thank you for your questions! Please find the answers below.

1- Do you have login to site with Linkedin? I mean user can login to site with linkedin and comment will be ready directly. ? I am asking this specially for directory theme sites. Would like to use this comment for my directory sites.

--> A website visitor who wants to comment with LinkedIn, will need to login with their LinkedIn account first before they can place the comment. If the visitor logs in with LinkedIn, they are giving your site permission to use their account for commenting. Your website visitor only will have to do this once. If he/she visits your site again later (with the same device), it's not needed to log in again and he/she can place a comment immediately.

You can see this process in this 2-minute video: https://www.youtube.com/watch?v=Xx1g6txJdMw&t=1s
And also test it for yourself on our demo page here: https://wplinkpress.com/demo

2- You mentioned in comments ''Unlimited'' options but I dont see in the deal. How many code we should stack for unlimited sites?

--> On the bottom of the deal page you will see a list of features which are included if you buy a code through AppSumo. The last 2 points are talking about code stacking.
- 2 codes gives you a lifetime license for 5 websites
- 3 codes gives you a lifetime license for an unlimited amount of websites.

Please let us know if you have any further questions!
