I'd like to send mails to about 10 members. In ordinary mail I may write down 10 addresses, separated by commas. But in xenforo this simple task become much more complicated: Create special group and add selected users to it; In ACP -> Users -> Email Users make mass mail for this group; Remove group or users from it. Why I cannot specify members in "User names" field? Ok, it allows name mask, it maybe useful, but simple list is useful too. Improve it, please!
