Good idea .. but honestly .. can you tell how good your "IT knowledge" is on a scale from 1 to 7?

Would it be possible to have next to names on the forum level of  IT knowledge.
Something like beginner, intermediate and advance. So when somebody asks questions it should be easier to answer if you have an idea what is their knowledge level.
I think this would help newcomers and everybody to be more helpful.
Ratings which we have  on the forum based on the number of post does not tell you very much of someones IT knowledge.
Please let me know what you think.
Thanks  :)
