no I have not, it is this week i'm both excited and panicked
provided you have re-read all the requirements and bring all supporting documents, you will be alright. Is it in KL?
In my case, i had no assistance from anyone back then (and had not found this forum) - and i made through just fine (albeit i am having some difficulties now - but that is a separate issue - haha).
And i did not provide them with my Certificate of Good conduct when i went to the interview and had to submit it later on (via Aramex, did not have to go to the consular ever again after that).
