docalexMany people seem to be having problems with the Suggested Tags feature of Simple Tags in WP v. 2.7
And I was one of them. However, while I had upgraded WP to 2.7, I had not upgraded my theme (which I'd been using since like WP 1.5).
When I upgraded my theme to a 2.7-compatible one, the Suggest Tags feature is working perfectly, popping up local, yahoo, and tag-the-net tags the way it is supposed to.
So, if you are using WP 2.7, and Simple Tags 1.6.4 suggested tags feature is not working right, consider upgrading your theme if it is an older one.
