List of Default System Accounts and Their Uses

Is there a list somewhere I'm missing that shows a list of the possible default accounts in NetSuite and what their uses are?  Some are of course obvious (Accounts Receivable, Payable, etc), but some are not (UnCategorized Expense?  Professional Tax?)  Someone noted on another thread that you can get a list off of SuiteAnswers by searching "Merging Accounts" which is partially true in that you can get a list, though incomplete.  No explanation for use though.

It would be nice if there was a SuiteAnswer that listed each possible system account, what type of transaction it is used on by default, and if it's there out of the box or if it will appear based on some criteria.  For instance, Customer Deposits is "hidden" until the first time you save a Customer Deposit transaction.
