Mac User Group has a great way of distributing its membership cards to new or renewing members: in the form of a thank-you email & receipt, with the card being at the bottom of the email. The trick is to print the entire thing onto a sheet of A4 paper & cut out the card section. Card sleeves are available at the monthly meeting and at two of the three shorter-duration satellite groups later innthe month. Alternatively they can me laminated at the main monthly meeting.
Finally got mine sent today, 5 weeks after I paid my membership fee. Already printed, cut out & laminated.
