Parked domains?


I have quite a few spare parked domains
Any suggestions what I can do with make use of them?

thanks for any feed back!
Mine that I don't use I just hold on to. A lot of people put those dumb ad pages up, but that just adds garbage to the internet.

You could sell them or redirect them to one of your domains that you do use?
I have no plans to sell mine, I want to hold on to them for as long as I can. I've had few emails from potential buyers...but it doesn't interest me atm
lol I'm trying to avoid plastering it with ads.. currently they are being redirected to my main projects.. some I've created into portal - type redirect index pages ..plenty of disk space, plenty of domains - just brain dead on ideas lol!

I even managed to rent a domain out for a while..But as soon as the person got bored..I was back to square one grr
I set up a few corny pages from image hosting /glitter makers and other nonsense items - but cant think of anything else
yet overall I also don't want to use up every bit of resource i do have killing the server...but something to keep few domains active, some how...
