There are two aspects to the greenwoodplace.org domain email system. The "everyone" mailing list, and permanent email aliases. I'll go into each below. To avoid evil spammers from harvesting this page and others for email addresses, I will not spell out exactly the email addresses, but I trust you will know what I mean.
Everyone at Greenwood Place dot org
The "everyone at greenwoodplace dot org" mailing list is now a "real" mailing list. By "real", I mean you can control certain aspects of the list via commands sent via email. The commands are send to an email address starting with the name of the list ("everyone"), followed by a dash and the command. To find out more, send mail to "everyone-help at greenwoodplace.org". The most often used are to subscribe or unsubscribe from the list. No longer will you have to let me know if you want to join or leave the list. Just send email to "everyone-subscribe at greenwoodplace dot org" or "everyone-unsubscribe at ...".
One thing I should mention is that I have set this up so only people subscribed to the list can send to it. This is to try and prevent spammers and email virii from polluting the list. Mail from non-subscribers will come to a moderator (currently just me, but I can add others) for approval. If you want to send from an email address other than the one you are subscribed to, simply subscribe with that address. If your address changes, subscribe the new address and unsubscribe the old address.
Permanant E-mail Aliases
The other aspect of the email system is permanent email aliases. Think of am email alias as being similar to the change of address forwarding that the post office has when you move. Mail to one address shows up at another mailbox.
I have set everyone up with a "first.last at greenwoodplace dot org" alias based on the email addresses I know as of today. Unlike before, the everyone mailing list is not based on these aliases so you will need to handle these separately. I don't yet have a way you can update the aliases by yourself at this time. It is easy for me to do, so just let me know.
How does this relate to the web site login?
The web site login is unrelated to the way the email works. It is a way for people to add content to the web site. For example, you can add new items, events, or your own photo albums.
You don't really need a web site login at this point. Eventually I may put content that we want hidden that would require a web login. For now, if you aren't sure if you need a web site login, you probably don't need it.
Still confused?
If any of this doesn't make sense to you, or you need help in any way, just let me know.
