I just bought 3 new domains and 1 expired domains, this is my first time to have a business in domains. Please appraise for few of my new domains... www.zno3.com - zinc trioxide, its familiar if you know chemistry www.woodfilm.com - I just bought for reg free, it said that have PR3 but... I think im dumb to bought it and still dont know what is the best for it. www.inlongwood.com - PR3 and dont know what is best for this domain name or blog content...
Yeah, not really the best start. I'd say the most valuable one, like MelogKnaj said, is KNO3, for the same reason. Don't give up! Keep trying!
