So, Iains, who determines what is thread drift and what is valid in terms of the thread topic. Certainly not the likes of me or or you. A thread often oscillates back and forth between the sublime and the ridiculous. The rule on moderation here is as little as possible. It is only when things get seriously nasty that threads get closed and posts get deleted. There is certainly nothing remotely nasty in anything about flowers or wine or scenery. There has been a lot of nastiness from some and some tongue in cheek banter between all parties. You have no right whatsoever to try to define the rules of what can and cannot be posted. If you have any complaints you can always ask the moderators to delete any nastiness. Deleting off topic posts on any thread would be a nightmare that I do not think anyone would willingly get involved in though.

In my opinion
