Hi all, WE Dictionaries are now supported on ATN. Additionally, all legacy dictionaries were migrated. New versions with the suffix 'webext' were uploaded as you can see <https://addons.thunderbird.net/en-US/thunderbird/addon/us-english-dictionary/versions/>. The list of significant (>100 users) dictionaries that couldn't be migrated is just 4, listed here <https://github.com/thundernest/addons-server/issues/66#issuecomment-474218782>. The total that weren't possible to migrate is just above it, but most of them have 0-1 users and are clearly abandoned.  Migration was based on the known language codes on ATN, so dictionaries that didn't have a clear target locale in their file names were not migrated. Note for reviewers: These newly added versions don't require review or approval confirmation.
