Actually sometimes we post in a thread or there is some useful information by other members too in the thread but the since starter of the thread (OP Post) is not up to certain standard and is deleted and hence all the posts in the thread get deleted.[/color
Thats a real unfortunate actually. However no matter quality the response on a certain thread, its a practice that once an OP thread is deleted due to lack of substantial important post then it goes directly to the trashcan, which include all the post of other users. So its a good practice before any user to respond to the topic, is think if the idea or subject is already redundant or low one, if its then dont reply at all cause chance that the thread could be deleted is high.
Always scout a new post that are pretty interesting and worth giving a shot to comment on.
