Seahorse is a GNOME frontend for the GnuPG utility. This program is quite nice but, unfortunately, it has been unmaintained for a long time.

I've just seen in the main page of the program that they are looking for someone to take over the project maintainership. This post is just a call for volunteers. I would like to help that project (it seems a nice way to get more involved in GNOME), but I feel I don't have the time to do it :( And it could be good to have an up-to-date program that can compete with kgpg.

If you are interested, look through the list of open bugs; you'll see that there are a bunch of interesting patches sitting there, waiting for integration in the project's mainstream code. This could be a good place to start if you decide to take over the project; that is, review those patches and integrate them, publishing a new version afterwards.
