There was a thread which I had 2 posts in it but after 1 hour seems no where to be found, couldn't find my posts nothing at all.
Well, AFAIK, any posts in the Trashcan aren't viewable in your posts history.
Is this common in this forum?
Threads being deleted/moved to the Trashcan are a usual thing on this forum.
I know when a post gets deleted you receive a PM telling you about it but how come I didn't get anything at all?
If the whole thread was deleted and there are some posts posted by you in the thread, but if you are not the thread starter, you won't be notified.
