Can I change the role of Free Subscriber?

According to s2Member® General Options -> Open Registaration,
s2Member supports Free Subscribers ( at Level #0 ), along with four Primary Levels [1-4] of paid Membership.
If you want your visitors to be capable of registering absolutely free,
you will want to “allow” Open Registration. Whenever a visitor registers without paying,
they’ll automatically become a Free Subscriber, at Level #0.

Q1.
Is it possible to give the role as Author to free user(without payment) who register
on buddypress registration form( open registration)?

Q2.
In the case of defining Level#1 Members as special paid member, I would like to know the relationship between
WordPress role(e.g: Subscriber, Contributor, Author) and S2member role.

I would like to give the role as the Author to all members ,regardless paid member or not.

Hi Masanori,

s2Member only supports the WordPress Subscriber role.

All of the s2Member Levels have the Subscriber role capabilities. If you wish to change the s2Member Level role capabilities, you will need to use a 3rd party plugin such as the Role Editor plugin.

Hi Raam,
Thank you for your reply.

I will try to inspect a 3rd party plugin such as ‘user role editor’.

Masanori-san, if you edit your roles, you may want to read this article too: Knowledge Base » Locking s2Member Roles/Capabilities

I hope it helps. :)
