I just received the following message from astarmathsandphys (Mr. Paul)
"I have no objection to any language being used and never removed any topic, but I will leave it up to each moderator what to do and whatever they do I will support them''
This shows that there is no rule stating that only english could be spoken, therefore i dont know why your topic was removed, hopefully u will get an answer tommorow morning from the person that removed ur topic,
Thanks
