I have made a proposal at http://meta.wikimedia.org/wiki/Wikimark2 for a Wikimarkup v2. I was unsure where to mention that I'd made this proposal. I am also aware that an update to syntax isn't pertinent or desperately needed; nevertheless I'd like feedback on the ideas from the community. Like Wikitax, the proposal can become a non-MediaWiki-integrated language on its own, or, if there is support, it can indeed be the next base of MediaWiki wikitext.
Disclaimer! I'm not being a "noob" with funny ideas that disrupt unnecessarily - I would probably have thought that of me if I saw this post straight-off - I've just had what I believe is a good idea for a MediaWiki syntax which, regardless of status-quo, I thought might be interesting to some of you. Let me know what you think at my Wikipedia user:Alfakim.
