Help:I posted scores on the previous site, but now they don't appear on the composer's page. What happened to them?
They're probably still on CPDL, but you can't "see" them.
When CPDL was first transferred to wiki format, every edition was tranformed into a wiki page and imported. The main problem in the transfer occurred when two pieces had the exact same title and composer. Then the wiki page was overwritten.
If you wish, you can help fix this problem, just look here to see how to contribute.
