Thanks for your answer.
>(a) from Thread Rating
The whole idea behind it is something like an idea pool, where users can post their ideas and moderators can give this idea a status like "accepted" or"will be proofed" in form of icons. This Status Rating (which is viewable in the Thread View as an additional first column) should be set and altered only by moderators.
>(b) from Post Icon
Ok, that's a point I ignore (Stupid me

). But I want to choose more than one. Instead of radio buttons there should be checkboxes. This selection (one ore more message icons) should be seen in the Thread View. Not only one message icon.
The idea behind this is that users place their idea into a group which the idea belongs to, like "Development","Marketing". An idea can belong to more than one group.
I hope my wishes are a little more clear now. Again any hint would help me a lot. Thanks
