Dear all,

I'm new to oTree and am working my way through examples and documentation, so apologies if this has been asked before.

I am implementing a game in which players are paired (sender and receiver). The game is played over two periods (separated by about one hour in real time). In the second period, the senders will be new participants. However, the receivers will be the same individuals who played in the first period, and they will again act as receivers.

Could I get some advice on the best way to implement this in oTree?

If this were full stack, I would create individual "IDs" and use them to "log in" during each period, which would allow me to link all the data in the way I want. However, I understand this might be complex to implement in oTree.

Thank you all.

Best regards,  
Ed.
