> Semicolons are for when you really can't break two clauses into two sentences with a full stop; a full stop is better most of the time.

IIRC (it's been a while) there are 2 cases where a semi-colon is acceptable. One is when connecting two closely-related independent clauses (i.e. they could be two complete sentences on their own, or joined by a conjunction). The other is when separating items in a list, when the items themselves contain commas.
