soyeah, this has been a LOUD AND ANGRY bone of contention between several old-skool LJ users and the Powers What Be. (Myself included). Both of my LJs are paid accounts. Both of them are over the 1000-tag limit. You can tag entries with existing tags, but you can't add any new ones, and if you type a new one into the text box for "tags", it will just decide you didn't mean any of them, which is the part that makes me really steamed.

It's the reason I'm (supposedly, supposed to be) working on leaving LJ.
