Mutiny Community version 2.6 update development notes:
Bug Fix: In chat the /textread and /tr commands now work with user generated text files.
The commands /edit and /typo can now be used with the search term and replacement term wrapped in quotes, this allows you to have spaces in either.
In the previous release you can make text files in your area editable by other users.  In this version you can also allow any user to edit a file by adding the username *:
contrib myfile.txt *
whereas for a specific user you would do:
contrib myfile.txt Jimbob
and likewise the "uncontrib" command would remove an entry to the access list.
Also added (specifically in this version) is a way to black list specific people.  So for example if you did this:
contrib myfile.txt *
contrib myfile.txt -jimbob
then you've set up the file (myfile.txt) so that any user *except for jimbob* can edit it.
When in the textfile editor, if you use the /import command but don't give it a filename, it will list the file names available in your upload directory.
You can now use "/index links" to see the 100 most recent messages that contain textfile links.
If your connection gets dropped while writing a text file the file is automatically saved.
