The usual way to make a change is to do it. Tiki is a do-ocracy.

If you want to change a procedure, a way of coding, a way to make decisions, etc. Find the relevant wiki page, and edit it. If it doesn't exist, create it.

Once you are ready with your proposal, please contact the developers mailing list, which is the closest we have to a decision-making body :-)
