I've tried this hack, but when I only select an Additional Usergroup that only has 6 people in it, it instead emails all 1600 users.

Running v3.5.4 here with the hacks as listed by Marco and tylneyt.

I had to leave these lines below commented out as otherwise they would cause the crash smdani was seeing above.

$condition .= ' AND (' . implode(' OR ', $u_condition) . ')';
unset($u_condition);

Any help??

Thanks.
