Alright... most seem to be in favor, and I don't really see any points against. There is enough space on the server, so that shouldn't be an issue. Best way to test if it is a good idea is by enabling it.... enabled!
Another thing. I've increased the total space per user for the groups VIP and Member so they are as follows now:
Member group total upload space: 500 KB
Member group max size per post: unlimited (500kb)
VIP group total upload space: 5 MB
VIP group max size per post: unlimited (5MB)
