With the 1.1 release, we doubled the number of themes that come "out of the box" with BlogEngine.NET. Most of these new themes came from the community and we know that there are a lot more themes that people have made available on their own sites.
We would really like to collect information on themes that people have made available and put screenshots and links to these themes on this site. We think this site would make an ideal place for a master themes catalog and would make finding available themes easy for BlogEngine.NET users.
If you are interested in sharing your custom theme, please let us know in the comments. Someone from the team will get back to you soon and we'll work on getting your theme listed on this site. In the future, we hope to make listing and sharing themes an easier process for everyone, but we will start with comments and followup emails.
Hopefully, we'll have a few linked up by the end of the week!
