Create a subscription, need help :)

[Goodman_2020]

Hi,

maybe i didn't search enough but i don't want to make a mistake so i prefer to ask you the way to do what i want to do.

I want to create a new usergroup with custom permissions of course.
Every new registered user wil lgo in this group of users.
It will allow them to create a thread, see forum and thread but wont be allowed to answer thread, contact members by PM or emails.
To have those rights, they will have to pay a subscription for X months.
Once the subscription is paid, they are automatically part of another group of users (that have al lthe rights they didn't have before)

When the subscription end, they can renew it, and if they don't, they go back automatically in the limited usergroup.

It seems simple to do (i guess it is) but i don't know how

And as a matter of fact, i tried one time as a demo to create subscription, but i don't know where the option to pay appears for the members. I would like to have a message with a link on my forum redirecting to the method to pay, and also have a message with a link to the "palce" we can pay when they click to post a message or contact a member but can't do it (by defaut there is"you don't have engouh permissions etc. but it's not enough specific)

thx
