Currently, there is no real system other than: "I want to suggest something, so I'll suggest something".
Whilst there is nothing wrong with that (and it works rather well), I would rather see something with a bit more structure - so as not to waste Alex's time.
I suggest that we organise the suggestion part of the forum into two parts:
Suggestion Discussion - The sub forum in which suggestions are generated, discussed and refined by the community to a form that the majority of people agree on, Etc
Suggestion Proposal - After suggestions have been through the discussion phase and are ready to be suggested properly the new and improved suggestion would be posted here, for the Devs to consider at their leisure.
Thoughts?
