I like the idea, but I can see on or two problems, first I like to point out that I don't have anything against the other doms, but I can see that some one might ask a new sub to do something which might be to much for them or beyond they limits,

I think that some form of profile descript, which will allow the dom's to see that the limits and the no go areas are for each sub, before they ask them to do something.

I not shore if this has come up if so, sorry, but will all the subs who has register, will be advible to all Dom's to assigned a task too.
