Hello – if I work on this as part of the free trial, is it a simple process to then buy the upgrade to the .com version of the website, if I like what I designed in here? I’ve never done this before but I want to give it a shot for a project for my company.
It’s not a trial; most of the WordPress.com features are free permanently, with a couple of caveats. You can buy midtexmpact.com whenever you like (but so could anyone else, it’s not reserved specifically for you).
Lots of people keep the .wordpress.com subdomain version but there’s always the more “official” looking option of registering your own domain. It’s completely up to you!
