What is the best way to use extra storage space and bandwith?

I've small website, barely reaching 10% of its storage space and traffic. Every month, I don't want to waste space & traffic. What can I do with subdomains, other than forums? Image or file hosting? Any ideas?

 

There is something that I've done before -- I'm not sure if you're trying to monetize the space or not, but if you have the right audience an Oekaki could work...a little bit heavy on the bandwidth and space side, but it adds some interactivity without the monotony of a forum or something else.

http://en.wikipedia.org/wiki/Oekaki -- Tells what they are, and lists some free ones .

 

This sound interesting. Yes, you are right, it needs special audience.

 

do like me, launch a few proxy sites.. lol
Complete nuub with getting traffic to em, but a 10 day old site had about 5-6k uniques, and the other 4 like 1-2k total.. not to shabby.
