There are many places where you can publish all your source code. Here are two that I used:
Google Code: allows you to publish your code publicly with detailed download information. You can use this and google forumns to get a review and help. SVN access is easy to configure. You can add others to projects.
SourceForge: allows you to publish messages publicly and privately. SVN is simple again. Allows you to add other users to the project with read / write / edit permissions.
These two may not be the best places to get overview and help easily, but they are great for hosting and source control!
In addition, they have forums where you can point out your other projects and ask questions!
