My name is Sam and I've been on the limesurvey team for about a year now.
For 2.1 we are planning on a remake of the admin interface; we can definitely use help on this!
There are some other people on the team that have expressed interest in doing some design / interface work so it might become a team effort!
Since 2.1 will be a very big change we are not limited to keeping any design from the admin interface we currently have. If you have good ideas please share them, (@others: I know at least 1 of the others on this list already did some sketching, I'm not sure who did that so respond to this email!).
We have weekly developer meetings on tuesdays at 1300 UTC; please ping one of us in the IRC channel to get the password to the developer channel!
