e.g. vs i.e.
what is the exact proper way of incorporating the latin abbreviations i.e. and e.g., in other words do the follow a comma, preceed a comma, semicolon or what. Also should etc. always just be followed by one period? Also is it true that the registered trademark symbol should only be used in the first mention of a product in a document?

Note the typeface (roman or italic). Both e.g. and i.e. require a comma after the second period; however, you will find that not every writer follows the rule. Some writers even advise against using the comma: They see the comma as over punctuating an already heavily punctuated form.
If e.g. and i.e. function as conjunctive adverbs, introductory elements, then they are preceeded by a semi-colon (;).
