Ok, here it is.
Given the simple nature of this hack, I am embarassed to release this in the Full releases section. :D
This hack does not require any template modifications to the user profile view as it latches itself on one of the fields that gets displayed in there.
In member.php look for:
$profilefieldname="field$profilefield[profilefieldid]";
$profilefield[value]=$userinfo[$profilefieldname];
eval("\$customfields .= \"".gettemplate("getinfo_customfields")."\";");
And replace it with:
$profilefieldname="field$profilefield[profilefieldid]";
$profilefield[value]=$userinfo[$profilefieldname];
if(($bbuserinfo[usergroupid]==5) or ($bbuserinfo[usergroupid]==6) or ($bbuserinfo[usergroupid]==7)) {
$emailinfo = "<a href=\"mailto:$userinfo[email]\">$userinfo[email]</a><br>";
}
else {
$emailinfo = "";
}
eval("\$customfields .= \"".gettemplate("getinfo_customfields")."\";");
Let me know how it works out. :)
