What bothers me, is that a lot of people either rather will be motivated or polished, but not both... Every now and then i come across a profile text saying:
NO POLISH, NO POLISH, NO POLISH etc.
This is not what a profile text should be used for. Now my idea is the following
Make an option in your profile in which you can enable polish enable motivate or enable both. This could be radio buttons, so always one is selected.
This way people visiting can only do the allowed action(IE what you specified in your profile) and the profile text can be used as a profile text.
Something like this is already available, because the options get greyed out when there is nothing left to polish. So it shouldnt be to hard to implement.
