**** I own around 50 domains. However I only use about three of them at present.

As soon as I come up with an idea for a site, I will buy the domain, create a folder on my PC with an index page and maybe an images folder; then I sort a slot on my server for it, and then configure dreamweaver with all the details.

I don't know why I do that, but I guess it is just to make it easier for when the time comes (if it ever will) to put the idea live.
