I recently spoke with a business associate, in which we exchanged emails. After several failed attempts at sending a successful email, my associate smirked and told me its a common mistake that people misspell his email address, or rather he misspelled his email address because the original username was not available. My inquisitive behavior further lead me to the revelation that one of the words in his company name could also take on varying forms. Such as plural and singular, verb and so forth. This also reminds me of talking with another associate who had a very long email address and even acknowledged the fact during the conversation.
Common sense is a key factor, if you have to question it yourself, then its time for a change. If your email address or web address sticks out like a sore thumb, then its time for change. You are your best critic, DO NOT IGNORE IT, CHANGE IT! The faster you change it the easier it is down the road when you have acquired more business and will have to juggle between time management and productivity.
