Is there any way I can get the link at the bottom of posts (posted in [category name]) to go to my blog-specific category URL (thewink.wordpress.com/tag/category) instead of the general wordpress.com/tag/category?
Doubtful… that was just changed by the admin folks to reflect their new global tag system.
There seems to be a bit of support for the change although I have no clue why. There has also been some discussion over the confusion caused by the change so maybe it is something they are looking at. MAYBE.
