Well, for the moment I've had to suspend any new users from downloading sigs/scripts.
I've only got 20 gig hosting currently and this month, I've hit over 15 gig... so playing it safe, new users are suspened until I sort something out.
Please could everyone check that their scripts are downloading using the HEAD command i.e. only grabbing the downloads when they have changed.
Some users have been downloading the sigs regardless of changes and it's not really helping, while only users have made mistakes and are trying to download every minute :(
