@ApolloandDaphne like @Redcrayons I tend not to come on to the thread until I'm stuck/need some help.
But I do sympathise. If I'm giving someone else a hint, especially early in the day, I try to keep it oblique. (Or will offer a PM if I can't do that, so it can be a bit more obvious).
Trouble is, something that's oblique to one person may be obvious to another, depending entirely on the greens they already have!
