I am just trying to fix bug-2278,i.e, Add subscribe to all comments to the community management page bugs.dwscoalition.org/show_bug.cgi. I understood that the code need to be inserted in /dw/htdocs/community/manage.bml. Code :-

$ret .= BML::ml('Actionlink', {

'link'=>"<a href='/manage/tags?authas=$user'>$ML{'.commlist.tags'}</a>"}) . "  ";

$ret .= BML::ml('Actionlink', {

'link'=>"<a href='/manage/subscriptions/user?journal=$u->user'>Subscribe to all comments </a>"}) . "  ";

}

$ret .= "</td><td align='center'>";

Here $u->user is used as it is used in /dw/htdocs/userinfo.bml for the same purpose. But I guess, It cannot be used since its not any global variable. If I use $user instead of $u->user, it is directed to /manage/subscriptions/user?journal= <username> But in othercase it is directed to /manage/subscriptions/user?journal=<community name>. Which is not the same.

Another doubt is "Subscribe to all comments" in the above code is working properly but other similar links are implemented as $ML{'.commlist.tags'}, etc.. So should I implement it in that way so that it will be in a standard way ? That would need a new entry in commlist which I guess is defined in /dw/htdocs/accountstatus.bml. Code :-

if ( @warn_comm_ids ) {

my $commlist = '<ul>';

$commlist .= '<li>' . $_->ljuser_display . '</li>'

foreach values %{ LJ::load_userids( @warn_comm_ids ) };

$commlist .= '</ul>';

How can I add "Subscribe to all comments" to commlist ? So that I can use it as something like $ML{'.commlist.Subscribe to all comments'}. I am not sure what I understood is correct? I could very well be wrong. Any suggestions on this will be really helpful..
