I think we just need to try and keep stuff to the most appropriate place on the forum. Moderators will try and move/merge threads and posts where appropriate, but it's impossible for us to spot everything.

ASX_Terranova enjoys doing and sharing some of the more fictional ideas, but it'd be helpful to keep them in the Fictional Service Ideas thread. 
For more general (and realistic) tweaks/suggestions to existing networks, then there's the suggestions threads for each of the big three operators.

Thanks!
