saving model

Hi all, how can i save a model fully rigged with all textures and particl sytems
so i can bring it back into a scene for animation with other models
or should i use the layers

just make the objects you want into a group, and save the file normally. then when you need that group of objects, hit shift F1 to append them to the new file. alternatively, you can start a fresh scene ( add scene at top of screen ) and link to object, or group of objects from the other scene. I think the way is to select the object(s) and hit ctrl L for the links menu. I have been known to get that command wrong, so may wish to double checkā€¦
(edit) you can also append an entire scene from an external file.
