Ok I spent some time fixing and updating some of the Cosmos addons for the Cosmos users. You can find them here
Cosmos UI for World of Warcraft the ones that say interface number 30000 all work.
A lot have been picked up by other people such as EasyMail is being updated on Curse and FluidFrames is on WoW Interface, so take the time over the next couple patches while these temp updates hold to find updates for the addons on sites other than CosmosUI.
