1a.) Can we change the default cover page? If yes how?

Not too sure what do you mean here but I am guessing that you are referring to this settings? http://take.ms/GiLnf

1b.) Can we also define a different cover page for different user profile types? If yes how?

I believe you are referring to this? http://take.ms/Gi0Vz

2.) Can we block that users change the default cover page?

Currently users cannot change the default tab. It is only available in the back end.

3.) What might be great here is to combine points and badges with the feature. So if the user has x points then he got the badge cover designer or something and can then change his cover. This might prevent the system from adding background pictures which aren´t that "nice". The user must then be part from the community longer then 5 days until he can do that.

That seems like a pretty cool idea.

Hm sorry I think i had to explain that in more words as using the therm "page" as "generall website" caused miss understandings with the "page feature" so let me retry (and adjust my posting):

1a.)
I would like to define a default cover image for user profiles. That means I would like to upload a picture which can be used as default profile cover background for all user profiles. I can overwrite the default image in the component, but every easy social upgrade will destroy that. So having an option to put a own default cover image in the environment would be great.

1b.)
Similar request as above, however I would like to define different default cover images for different profile types. For example I have two profile types. Moderators and Users. Then I would like to use a red default cover image for the users profile for the moderators profile and a yellow one for the users.

2.)
I would like to prevent that users can upload a own cover page on there profile page. This is to prevent that they upload some not so "nice" backgrounds/cover images.

3.)
You are welcome I moved that into a feature request here

Hi there,

Kindly find my response for your inquiries below:

-> You actually can do template override for the default cover.
Refer this documentation: https://stackideas.com/docs/easysocial/administrators/templating/overriding-default-cover

-> Unfortunately, it is not possible to make different cover photo in each profile type currently.

-> There is no setting to disable upload cover photo currently.
