Reading through everything, no. It only says "make proposals". It also mentions checking out votes and how your votes in the discussions will help determine if you are ready to become a trusted user and do proposals yourself. You need 301 contributions to vote. Once that happens, you can try and give good justifications for your votes. Do that, build up another 200 contributions, remain here for 5 months, and find ways to help the site and prove yourself a valuable asset, and than you can do proposals yourself.

Until then, I suppose you could ask admins/mods (aren't those the same thing) for advice on how to help the wiki and prove yourself. Until you prove yourself, keep rough drafts for any proposals you plan in your blogs, and either see if any trusted users on here are interested in doing the proposal on your behalf, or keep it safe there until you can do it yourself.
