Trion Worlds just announced in a press release that it has extended its Founder's Subscription Plan for Rift until March 31. This means you have a little bit longer to lock in to a discounted multi-month subscription plan.

As part of the Founder's Plan, you can choose the 6-month subscription option and only pay $9.99 per month. That's currently the cheapest way to pay for Rift, so you may want to pick that plan by the end of the month.
