Some time in early May, a commit was made, and the author wrote me a message reminding me to revisit it when the first-class aggregate feature was complete. The message had this link: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080505/061979.html Clicking on it today, I find a commit that has nothing to do with the feature. Hunting around, I believe I found the intended commit, which is a few messages later in the archive: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080505/061981.html Similarly, what was recorded as http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080428/061905.html seems to have moved to http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080428/061906.html And http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080428/061863.html seems to have moved to http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20080428/061865.html I don't have specifics, but I believe I've seen other archive links change like this. Did the archive get re-indexed, or have there been any other changes? Thanks, Dan
