Since the site's Membership is administered by MemberPress, it is apparently overly complicated to enable Membership Renewal before it actually expires. (Custom coding out-of-box sftw solutions is done at some risk to overall health!)
As a result and for the forseeable future, Membership renewal may only take place once current Membership has expired.
Once your membership
has expired, you can renew by visiting
this page.• If you have
Auto-Renew enabled (the default) and a
valid credit card or PayPal account set up within your account, your membership will be automatically renewed.
• If you have a complimentary membership, please renew
after your membership has expired.
• The
Auto Renew feature may be turned On or Off by Members in their account settings as desired.
