Hello,
Please see my replies below:
1. Members
Front page
Login
Register
Lost password
create a profile with some fields + upload files
update profile
s2Member uses the WordPress login and authentication system, so Login, Register, and Lost Password are all taken care of through WordPress. (With s2Member Pro, you can use the Pro-Forms feature to create your own registration forms instead of using the WordPress signup page.)
s2Member allows you to create custom registration/profile fields (see Dashboard -› s2Member® -› General Options -› Registration/Profile Fields) and has a profile editor, however there is not currently a feature for uploading files.
2.forms
easy build forms
Yes, s2Member Pro comes with the Pro-Forms feature which allows you to create your own registration forms. Custom Registration/Profile Fields can be created to show on these forms.
3. Export/import data
user data and forms data to excel or csv
Yes, s2Member Pro includes an import/export feature.
4. s2member Pro have trial or demo to test all Features?
Yes, s2Member Framework is free and creates the base for s2Member Pro. All features in s2Member Framework are included in s2Member Pro and we recommend downloading and installing the Framework first to see if s2Member fits your needs.
5. Are available service integrate/implementation/custom on website?
No, we do not provide custom integration services. If you need to hire a programmer to assist with setting up s2Member, we recommend searching jobs.wordpress.net.
