All my email accounts are web-based, for ease of access. I couldn't even begin to remember my ISP email details
Could be a useful tool - e.g. keep all bike-related contacts on the BM email. I've started filtering my contacts and using different email addresses for different types of contact, so as to avoid losing business stuff among the personal.
If the set-up cost is prohibitively high for you though, I'd personally be inclined to sit on the idea for a while and maybe roll it out later in the year - see how the membership take-up goes?
