Too much autolinking
Version 4.0.0 autolinks to the titles of subect area pages. This is a change in behavior that is confusing users.
This may not be a bug and in our Wiki there is an easy workaround.
The subject areas in MAIN are being autolinked in our forums. I believe it started with 4.0.0. Was that intentional? I can put all those subject titles into the ignore list, but in a larger wiki it could be a problem.
