Sometime Tuesday morning, all of the Plus memberships automatically granted to testers for testing purposes will be removed. To ensure uninterrupted access to your Plus features, you can purchase (via credit card or PayPal) a Plus membership before that time. Don't forget that right now we have a buy one, get one free offer, so for only $25 you get two memberships!
You can purchase BitWise Plus using Web Services.
The testers who won memberships, the translators, and other media contributors have already been granted permanent memberships. Logging into Web Services and clicking on the Plus icon will tell you if you are already a Plus member.
Feel free to post any questions about Plus memberships in the Testers' Place if you have any. Thanks!
