i got like around 2500 domains. 1k .com and other international tdl mostly .ins
reg fee is killing me. Developing some to break even the renewal fee.
But can't resist to buy good bargains. buying .orgs and .net generics, if you have some pls pm me.
LoL, lease your domains to me, I'll add a proxy on it, we do the google ads 50/50 (You may have 2 adsense users on one site) and I'm sure you will have earned enough for the renewal fees
You'll gain pagerank & alexa with it too btw
