Gnatsweb is looking for a maintainer. If you're interested, please take a look at this general information about GNU packages and being a GNU maintainer, and then email maintainers@gnu.org with a bit about your background and interest. Thanks!
Gnats itself could also use development help or a co-maintainer. Same applies.
