Hi experts!

Does anybody know if it's possible to do a repeated measures design with LimeSurvey?

In order to determine the validity of a psychol. test we want to have the first measurement with the full test version and 2 weeks later a second one with a shortened AND modified version.

1. Is this possible within one survey, or do I have to create two seperate surveys?
2. Is there a possibility that each participant gets an invitation mail to the second part of the study after two weeks automatically and individually? So that it would not be necessary to check for each participant when two weeks are over?

We are working with Version 2.05+ Build 140520.

Sorry for mistakes, my english is not the best. Hopefully the questions are undertstandable and somebody can help!
