What? Are you absolutely sure about this? To my knowledge, the RSA lookback period is 6 months, not two weeks. That's 12 times as long as you claim. In the past, I regularly got PoR payments stretching back more than 3 months.
This information is also reflected in the Gridcoin wiki, in the Proof-of-Research article: http://wiki.gridcoin.us/Proof-of-Research
If you have information that the 6 month lookback period for Proof of Research is not true any more, it would be important to state this (and a credible source); as it is now, this post will only lead to confusion, which is not helpful (especially for newcomers).
Moreover, I think it is especially crucial to give correct information when posting headlines starting with something like "IMPORTANT". As experienced Gridcoin community members, we need to set an example for newcomers, and adhere to accurate and neutral reporting of any possible issues.
It's a 6 month lookback, erkan is misunderstanding how Gridcoin works. Rob just confirmed this on Slack.
