I've heard from quite a few frustrated people that they feel the pre-proposal process is hard to follow.  I think this change is good because it will give more people a chance to weigh in on legit proposals.  I agree that if you can get 5% of the total SPS in votes, then you have a proposal that should be considered.

I also think your point about making changes to the pre-proposal is not well known.  Some feel that if changes are made, then a new proposal must be put forth.  I can see both sides and feel that this is something you might want to re-iterate the next time you are on a town hall.

Overall I support any process that lets the community decide issues via good governance, and this I believe will give more SPS holders a voice since they will see the proposals via the ingame notifications.
