I have 2 unused PR2 domains, what should I do with them? How hard is it to get PR2 because I didn't do any backlinks work and got it Do I just let me expire and or turn it into a directory? Thanks.
PR2 is relatively easy to get, so it would have to be a keyword domain in order for it to be worth $$$.
Try to Sell them in Buy/Sell section, or else give away for free, unless the names are good and usable.
make a directory or blog and make some money selling links, then sell that and the site along with it later, make profit
