If you have attempted to pay online with no avail, it is probably because, once you click on the pay button, a popup screen opens up for the affinity payment portal. 

These days, you have to allow the popup, because security on web browsers is top notch. If you don't quickly click to allow, it can be difficult to complete depending on the browser.

If you'd rather just send a membership dues check, then mail the $50, 2026 membership dues to me at:
MGGA
C/O James Fashing
206 E. Sims St. 
Centralia, MO 65240

I will email a receipt and mark the membership paid.
