I haven't finalized the permissions on the Gallery yet. Or haven't made up my mind on how I want to handle uploads. I can choose to let each user have their own album (which would show under the main albums) but I'm leaning towards having them upload into the main gallery instead. As of today you should be able to upload into one of the main albums like "weather" or "landscapes". I will turn on user galleries temporarily so you can see the what it looks like.
I have a big concern about what people (or spammers) will upload. We don't want inappropriate material! I have created 2 user groups. The first is what a member becomes by default when they first register. Anything they upload will have to be approved first before is appears. Then when I see that they are a "trusted" source I will promoted them to the level 2 group which will allow them to upload with no approval.
All this is why I haven't allowed anybody to view without registering yet because I want to get this all finalized before the average visitor can browse.
