This feature will go a long way in increasing recruitment, marketing, FUNraisers, etc. Not to push the envelope, but the ability to create email addresses and dist list on the fly would be even more awesome. There could be one address for general contact (firstname.lastname@example.org), one address for recruitment (email@example.com), you could create an address for specific activities where outsiders are invited (firstname.lastname@example.org, email@example.com), etc. rather than giving out the email address of individual persons. The addresses could be activated and deactivated as necessary (like for recurring events such as the barefoot mailman) or just deactivated when no longer needed (such as the Florida caverns event).
This would also allow for consistency as old leaders move on and new leaders are added, the change would be transparent to the members since the address would be the same but the dist. list would change.
