Maillist2RSS
Mailing lists is a one of the most popular ways to get support for many open source projects. But it’s not so comfortable for me (I prefer RSS). Recently I found very interesting project – Gmane. It’s translate mailing lists to the web and offers RSS channels for them. There is a possibility to add a new mailing lists if it’s not presented in Gmane. As advanced service Gmane allows to make a search in the mailing lists which is very very useful because there is no way to find something quickly in the mailing lists archives.
