I've only just heard of this new system they're using. i've noticed many selling these rapids on here and i'm just trying to get to grips with it. i understand its 99 rapids for 30gb of traffic to be used in 30 days, so if i had hundreds of rapids in my account do they have to be used in a certain time or as and when i choose? and is it safe to buy these outside of rapidshare.com? thanks in advance
