Click your account profile at the top of the page, should have a menu pop up and there's an "account upgrades" that will get you to the subscription page.
After a discussion with @Trunks0 we've decided to lift the requirement to be a subscriber to access the Politics & Religion forum. This decision was made based on the current political climate in the United States.
It is expected that we follow the rules in that sub-forum and above all to treat each other with respect.
It is also no longer a requirement to "Join" the P&R forum, this was a requirement on the old forum software, now as long as you are a member you can participate in the forum.
