The off topic stuff does provide light relief and I find that posters generally refrain from such antics if asked politely to keep it on topic.
I don't find the clinical ones go off topic until the relevant points have been covered.
A massively off topic post usually indicates that it has lost peoples interest surely?
I am not as guilty as some, and they have already said that they know who they are, but I have been known to stray off topic myself on occasion so I guess i can't condemn too much
I like the light moderator touch - I'd hate to see threads stopped just because they go off topic. I don't get to log in very often so often come into a thread rather late. I'd miss quite a lot of useful stuff if they were more heavily moderated.
perhaps the OP could say when they feel that a post is being hijacked inappropriately?
We are all (generally) grown up and don't (usually) offend on purpose but the problem with forums is that we only have the written word. it is a peculiar form of communication without all the usual cues that we get from face to face or even telephone conversation.
