OK, just tried it, and it's very easy to screw up the site layout by allowing HTML inserts... total mess. A potential security issue too.... can't remember if HTML can be disabled from the admin panel.
Well, a partner and I are planning on deploying a site ... still evaluating k-rate. It seems nice, but it IS a 1.0 product so..... a wide variety of features that are very interesting.
My concerns:
1) Ongoing product development and support
2) Security (what if a hole is discovered....)
3) How long had turn-k been around...
