ok - thanks guys - I guess that means that I will post this (have to translate to french - confusion is a little higher for the people that can' read english^^) on our guilde site.
WoWAce serveur no longer will be hosting updated addons on their serveur, and recommends author hosting at Curse gaming server. WoWAce recommends you go to curse for latest versions.
If you have been loading your addons with the library files "non-embeded" (option no external for updaters -- 1) backup your addon directory 2) delete libray directories (names beginnin with Lib*) 3) re-download all addons manually to ensure library files are embeded in the folder of each mod
Updaters using wowace serveurs, although in development, will not fucntion except to download the last available versions posted on the WoWAce serveur before it was locked. This could be very temporary too.
It is highly recommended to not wait to start downloading > patch 3.0x addons, as traffic will be very dense near patch day at Curse (save to different folder^^ will not work until the patch is in place.
Is this about right?? If i start telling them that some version will be available without embeds, they will just get confused and not update their adds I think or screw up.
