I have a lot of domains that consist of NLN or NNL (.net/.org/.info). I use the .info ones for proxies, but I don't know what to do with the rest. Those domains are 4 years old or 5, but I have never developed them :/ I am not quite sure if being aged even means anything for those random names... Please help. Thank you
3 characters is pretty good. All i can say is hang on to them as they should only increase in value as a domain name. In theory the smally renewal fees should be dwarfed by the selloff value in "X" years time. adding some content would not likely increase resale value. you could put a page on them offerring to rent out the use of the domain, thats a new way to make recurring money from domains.
