Hi my E-mail provider is being blocked by this site for some reason. What's up with that?
There's no technical possibility for you participation at this site to block your email. What could happen is that your email provider could filter any or some email notifications sent from this site, usually for the reason of "spam filtering".
In any way, the emails (except for one account activation email email sent to you at the very beginning of you membership) , are not necessary for you to operate imodeler. You can find all updates, comments or private messages directly at the site.
