Frequently Asked Questions about GuildPortal Hosting

Q: Can I subscribe, and then immediately cancel, to avoid recurring charges?

Yes.  Many guilds do this, and your guild won't be made a non-subscriber until the full 6 months has expired.  This doesn't apply to guilds contesting charges, just cancelling the subscription.
