...which in fact pretty much tells me nothing at all...
Short answer: if so, stick to sRGB.
Long answer: Depends on whether you shoot RAW or jpeg. Also depends on your desired output, i.e., whether you post-process your images (in Photoshop or similar), and whether you print them at home or online lab, or you simply upload them to web sites.
If you shoot RAW, the camera setting (i.e. Adobe RGB vs. sRGB) does not matter (but might influence how accurately camera LCD displays pictures)
If you shoot jpeg, intend to post-process it and print at home, go Adobe RGB
If you shoot jpeg, intend to post-process it, but want to print it online (or send to web sites), set your camera to Adobe RGB, process it as such, and convert to sRGB as the last step in post-processing
If you shoot jpeg, but do not want to post-process it, just to use it on the web or for online lab printing, stick to sRGB
These are simplified, rule-of-thumb suggestions, that take into account your current apparent knowledge of the subject (as perceived by me, of course). I hope you'll find them helpful.
