Like I recently posted on aMule's board "I wanted to suggest some additional file formats that could be, IMHO, usefully recognized. I'm thinking to OOo files and Ogg Theora videos along with a couple of other formats (...) I performed a global search for all of the file types and there were results (...)". Apparently I'm soooo sexy that they accepted it, and I thought it would make sense to check your CVS and propose a very similar patch as well. Its purpose is to give the users the ability to find and share more files which are also free formats that are not DRM infested.
For additional details please see the
Here's the archive containing the patch and the modified file, plus the patch and the modified ed2k_filetype.cpp at pastebin.ca in plain text form for your convenience.
All the best.
