:sigh: 
you'll understand if you've been through it all
... all the repeated posts, failed reconciliations ...
Anyway, can't help with the past already. Now there's a problem,
either we solve it, or leave it be and let the situation mess up
the forum.
If really can't help it, some of us won't mind leaving and find
a quieter place to share our ideas.
That's what I did. I went over to the other forum, at
Skyscrapercity Singapore forum. Then I got discriminated, and I
decided to come back to SGforums. Probably because the people at
Skyscrapercity thought that I am "Path Light", since 'Pioneerboy'
really does sound like "Path Light", that's why. KNN. :(
Anyway, rather than write here, you could write email to your
MP, or to the LTA, if you have comments or suggestions about
Transport. Tried before. The reply from LTA takes around one month
to come back, probably because there are many people who write to
them. The reply from MP, on the other hand, takes around one to two
weeks.
Of course, if one send spam email or write nonsense to them, he
may be "black-listed", where his emails would be sent to the
'trash' section of their email.
Actually, why not just stay on here at SGforums? In my opinion,
except on trains, SGforums is established on everything.
I believe the administrators can edit and remove replies. If
anyone's reply is not appropriate to the thread topic, the
administrator may remove it. Once he realise his replies keep being
removed, he may stop replying, or even start to write replies that
are appropriate to the thead topic.
This should be the approach to take, rather than do nothing to
stop the people here from isolating any member here.
