Hi, there are some features which could boost the group functionality x-fold. Right now a group is a container for messages sorted forum-style by last comment and equiped with a "send message to all" feature.

The most important function I miss: A different sorting order for posts, especially according to publication date. E.g., in the 红楼梦 group, we follow the novel sequentually and the sequence is important to find old discussions again or to re-start from the top. Now you can still handle it with 20+ posts - but we haven't even finished a quarter of the first chapter. With 200+ or even 2000+ posts sequentially sorting will become a critical success factor.

Furthermore: It would be really cool to have a group-dictionary - which could in the very least be a shared vocab set that can be flexibly expanded and looked up.

I would really appreciate the following additional options for posts in group sections:

• Unlimited change time
  Most of the group contents are not "blog discussion" which require meticulous archiving but content collections where mistakes might be discovered months after the publication. 
• "Invisible" posts & changes
  Some posts are not relevant to appear in the main Conversation section - they are just supplemental. For example it hurts that each time I add a CSV-list to goulnik's excellent tables this bombs into the main conversation lists. It is a minor add-on not something worthy to be made that public. 
• Open posts, wiki style
  There are some posts where I would like encourage each group member to add corrections or additions.
  Design options: With or without highlighting of changes. With or without history.
