For the last ten years or so, I used to maintain a list of conferences in the area of analysis & PDE (see e.g. this page for a partial archive of this conference list). However, due to many other demands on my time, I eventually ceased to maintain it, instead passing it over to the Harmonic Analysis and Related Problems (HARP) group that was supported by the European Mathematical Society. Unfortunately, the EMS funding ran out a few years back, the HARP group dissolved, and so the page drifted for a while.
This week, I talked to my good friend Jim Colliander (who maintains the DispersiveWiki) and he agreed to host a new version of the conferences page on the Wiki, where it can be collaboratively updated. It is rather sparse right now, but I hope people will contribute to it, either by adding new conferences and related content, or by cleaning up the organisation of existing content. I have also migrated a list of lecture notes and courses in analysis and PDE which is badly in need of updating.
[One can presumably use the Wiki to also host other items of this nature than just a conference list; any suggestions for expanding the page would also be welcome.]
