Just flicking thru the WT Nov 2006 and found a 2 page spread on how to give your money to them, this is quite something - just in case you were not quite sure how you could add to their funds:
Ways in which some choose to give
Contributions to the worldwide work(many set aside a budget)
Conditional-Donation trust arrangement
Charitable planningInsurance (WT named as beneficiary of life insurance policy/retirement/pension plan)
Stocks and bonds
Real Estate
Gift Annuitty
Wills and Trustsproperty or money bequeated to WT
Well they're certainly not shy in asking for it!
