I had a discussion about this recently: do you write ). or .)?
For example:
"Websites can be assigned to application pools, all application pools containing specific settings for applications (allowing you to isolate websites)."
Or:
"Websites can be assigned to application pools, all application pools containing specific settings for applications (allowing you to isolate websites.)"
AD precede the year, but let BC follow (small caps, no full stops).
