Q: Is there a Zip file with all the addins in? Why don't you create one?|
No. It could never be complete because several addin developers request that their addins are downloaded from their own websites and I respect their preference. This means that users will always have access to the latest update they have done and allows the developer to monitor the downloads of their addin.
Q: I've downloaded an addin and installed it on the rex but it appeared as a memo file?
