Anybody want to give me advice about semicolons? Not that I use them a lot (notice that?) on MT but in helping my son on his composition papers, I think I have led him astray. What's the rules on independent and dependent clauses and commas or semicolons again? I've been too long out of school. sigh! TW

I'm a copywriter among other things, so to me it's abhorrent to care too much about grammar on a forum. It's like work to me. However, internet posters in general do express concern about grammar, which is a good thing I suppose. I had an entertaining argument concerning this very topic on a sportbike forum, of all places.
So, here are some incomplete answers concerning commas and semi-colons:
In modern writing, commas are placed almost subjectively. They are used most commonly to indicate a small interruption of thought or sentence structure.
There are a few steadfast rules. Commas are obligatory when joining a compound sentence with a conjunction unless the clauses are really short and closely related. Commas are also used to set off nonrestrictive clauses, such as this clause I'm writing right now. Dependent clauses are also bracketed by commas. Adverbial phrases at the beginning of a sentence are also followed by a comma, unless the verb it modifies directly follows the phrase.
"That" is not generally preceded by a comma, "which" is. Parenthetical elements are often surrounded by commas if the sentence would lose meaning with their omission. It's in vogue to use em-dashes--those long dashes seen here--in these cases rather than commas.
There's more; I suggest looking at Strunk and White or another good style guide like the Chicago Manual of Style. In a pinch, speak a sentence out loud. Place the commas at the pauses. Reading a sentence out loud quickly reveals any flaws in its structure.
Semi-colons are used when connecting two parts of a compound sentence that don't have a conjunction linking them. They should also be used to separate items in lists that have items that are described within the list by subordinate phrases and broken by commas.
Semi-colons can also be used in place of i.e. (that is), e.g. (for example), and other expressions. Basically, they're commas that carry more emphasis. Again, check a style guide for more details.
