 [SIGMathLing members](/member/) but everyone is welcome to join (after signing the [SIGMathLing Non-Disclosure-Agreement](/nda/)).
 
 If you are a member, you should have access to the two repositories containing the data:
-* [https://gl.kwarc.info/SIGMathLing/ntcir10-math-understanding](https://gl.kwarc.info/SIGMathLing/ntcir10-math-understanding)
-    for NTCIR-10
-* [https://gl.kwarc.info/SIGMathLing/ntcir-11/](https://gl.kwarc.info/SIGMathLing/ntcir-11/)
-    for NTCIR-11 and NTCIR-12 (presumably, you will mostly be interested in the contents of `NTCIR/ntcir-math.nii.ac.jp/download`)
+  - [Download links](https://gl.kwarc.info/SIGMathLing/download-links/-/blob/main/README.md). This is a temporary solution as we are in the process of migrating the data.
+  - [SIGMathLing members](/member/) only. Joining is free and mostly a legal checkmark on our end - all researchers welcome!
