How to remove the OSMapper asking for Rating

Hello,

First of all I need to thank you for this wonderful WordPress Plugin, it works good on our site. Yes it is still in development and we are working hard to go live.

The only thing is every time when I log in on to the site. The OSMapper plugin is asking for a rating, I do click it away, but it comes back the next time I log in.

Is there a way to remove this ?

Thank in advance

Zoran
