Dear Community, 

I am having the following setup and I would need your creative ideas: 

I have multiple surveys that are identical however the content of the notification email differs based on the treatment condition. 

How to make the title of the survey distinguishable for me but not for the respondents? So I would like to call the survey, e.g. "Group 1", "Group 2" etc... but I don't want that the respondents see that as the title of the survey. 

Is there any alternative solution for that besides modifying the CSS files and opting not to display the title at all?

Thanks a lot in advance!

Best, 
Kor

You must check manual.limesurvey.org/Theme_editor and set the title here.

Else : vote up for this feature 18740: Have internal title (for admin) different than public title

What I do in such cases:
I distinguish by SurveyID.
When you copy the survey you are free to choose a SurveyID

So you may choose 
112201
112202
112203
...
112212

I have multiple surveys that are identical however the content of the notification email differs based on the treatment condition.

Why even setup different surveys if they are identical? The differences in the notification email can be solved by including custom attributes into the participant table and refer to them from within the email templates.

So you can have the same survey but change the treatment condition via expression script in the respective questions, as well as in the email templates.
