How about a “Themes” section, where you provide the reindeer and runo theme and users could send you their own themes to add? 
A very good idea, and this should definitely be baked into the “Directory” that’s in the works. I’ll try to persuade the r’n’d team to take this into consideration when planning it in the coming months.
But in the mean time, you can request commit access to the contribution area in our SVN repository, we’ll be happy to take any themes you might have to share!
