Question concerning Sight.

Just to be sure, do normal targeting rules apply? Or can I target anyone I can see?
You must follow targeting rules, this is covered in the glossary definition of sight.

OK, thanks. This glossary of which you speak, is that just a reference to all the glossaries in all the rule books, or is there a collective glossary somewhere with everything all in one place that I am unaware of?
The rulebook glossary.

For the most part, we reference the actual WOTC documents: Rulebook/glossary, inserts, FAQ, DCI Floor Rules.
Also, when the glossary is refrenced, it is the most recent glossary. Older ones do not have as many entries and some entries have become incorrect due to errata.
