It may take a day or two to be approved to the Facebook group. To protect the group we manually check that each request comes from a member and that the group rules have been accepted.
If your request remains pending after a few days (and it’s not the weekend), maybe either your email is missing from your request to join the group or the rules haven’t bee accepted.
You can correct by opening the link to the Facebook group and then clicking the button underneath the header image (it may say “Pending”):
Click that button and in the window that pops up make sure your email is entered into the field and the rule check box is checked and click submit again:
If you don’t enter your email or accept the group rules your request may not be approved.
