Add me in. Thank you.
To off-service: Even though LTA needs to confirm the number of
attendees, last minute additions are allowed.
I want to deter last minute additions to make logistics and
planning (like meet up timing) easier, at the minimum I know who to
expect.
Also, I also want to avoid large last minute turn ups, though
unlikely, but at any chance if the turn ups go beyond 40, I think
that would be a sticky situation to be in.
Hope everyone understands my intention
