I'm Sorry, but tag wikis are not an appropriate place to solicit followers. Advertising a proposal in a tag wiki would not be appropriate.
I know it sounds like a harmless bit of advertising, but there are thousands of proposals who want to be heard. Many have tried posting their announcements to our Q&A sites, adding comments to related questions, posting them throughout the meta site discussions, and even announcing them in related proposal subjects. It becomes very noisy fast.
We work hard to keep such solicitations out of our communities, and advertising a proposal in areas where such activities are discouraged will only encourage that same behavior from many many others.
I'm sorry, but advertising is not allowed in tag wikis.
