My personal feeling is that 10% ist still too much as reserve value for domains that you want to sell to others domainers. I will say 5% is the good value. But it's allways the same, more you lower this value and less you attract domainers to list their names and/or list quality names, and at the inverse more you increase the reserve and less sales you make.
The current submission form is going to be transformed in a bulk submission form, and to avoid hassles all the parameters have been set to default values. The listing date is the next day, the reserve is 10% and the domain description has been dropped.
The idea is in he following days build the bulk submission page and only in a second time can change in your account some values, like the reserve. This way we can make a submission page that is easy and fast for more of the "lazy" domainers or domainers that want to save time.
