Chips, you need to give docbrown your full name, as you gave TUG when you joined TUG. Then docbrown can tell TUG that you referred them when joining. TUG will send you confirmation a few days later, that you have received a referral bonus. Keep that email so you can keep track of your referral bonuses.
After that, when it's time for you to renew your annual TUG membership, or to place a TUG classified ad, or to purchase TUG merchandise, you can use the referral bonuses instead of payment. So post, email or PM docbrown with your info. HTH.
If Chips is not currently a TUG member, I'm always happy to receive TUG referral bonuses.

My name is Lisa Potter, (Lisa P on TUG). It's kind of you, docbrown, to give someone here a chance at a bonus.
