I have many email addresses. However, I've found that none of them work well over the phone; the letters or words are easily misheard, which ends up with me not receiving emails.
To remedy this, I decided to register a domain name composed only of unambiguous
characters. This program searches for words in /usr/share/dict/words for
entries solely composed of those letters, then does whois lookups to find
unregistered .com domains.
No command-line help. No commenting. No error handling. Domains with multiple
matching records (eg willow.com and willow.compsys.com.au) are reported as
available.
But it worked enough for me to find a domain name.
