I welcome any service that promotes email (over more proprietary solutions, be that Facebook Pages or some hosted groupware). That said, for a more technical crowd, your page(s) are a bit light on detail:<p>1) Do you provide an archive? Can it be public?<p>And while I usually tell people (based entirely on my intuition rather than actual business experience) to charge more -- where does the 100 members limit come from? Certain types of groups, like alumni from a single subject&#x2F;course&#x2F;small business&#x2F;hobby -- might organically grow past that point. Should they then migrate away from your service?<p>In general I wish you the best of luck - but for me (not really a target audience) -- I&#x27;d like to know how this compares to setting up a Mailman-list, D-lang forum or something along those lines for non-technical users? (Apart from the obvious, and undeniable value-add of you hosting the actual service).
