Can't you read my message ? Or aren't you intrested in my question ? Some people on the french's Wikipedia think that anchors are very important features and are waiting for your answer...
I seem to remember that Lee half-implemented anchors a while back, but they're not actually enabled. If nobody else can answer more fully, I'll go look over the code and see what still needs to be done.
Yes, they were fully implemented, but then I disabled them upon request and discussion by the list, because the syntax for specifying them was awkward and others felt the ability was premature and likely to be abused. I'm still working (slowly) on reforming wikitext syntax in general, so I hadn't gotten back to the issue of anchor syntax specifically, but if the list agrees to a syntax it will be trivial to re-enable the code.
The link code is in fact still present; [[page#anchor]] and [[#localanchor]] will produce a link exactly as expected. My original syntax for placing the anchor itself as [[##anchor]], but other suggestions are welcome.
