A room for discussion

An original notice containing five intentional errors.

The room are available after the main reading, but it has a separate booking limit. Participant's should contacts the desk if they want to attend the discussion as well as the larger event. A place in the hall does not garantee a place at the smaller table. The orginiser will confirm both requests clearly. Anyone who prefers not to join the conversation can still submit a written question.

Proofread the notice. Identify the five errors and write the correct forms. You do not need to rewrite the whole passage.
