Someone please help me! I’ve exhausted my search skills trying to find an answer to this question in relevant FAQ’s and forums. Someone else asked, but never seemed to get a response. I might need to upgrade my space in the near future to 1gb (won’t be able to afford anything larger), can someone please tell me if these “credits” you buy pay for this upgrade as a one-off fee or is this going to be a yearly or monthly subscription? I can afford $20 as a one-off, but if this is a monthly or yearly fee for more storage I will have to look into other options.
