These days, it can never hurt to be too careful with your domain names. People out there base their livelihoods on snatching up valuable and highly-used domain names in order to turn around and re-sell them at a high price.
You don’t want this to happen to your website. So, is your domain name on auto-renewal? Most domain services will put your domain on auto-renewal, but many old URLs are still on a manual renewal system which could mean that your domain could be in jeopardy next time it comes up for renewal. Make sure that you’re not stuck without a domain name!
