OK, what is the equivalent to statusnet's groups in pumpio ? I miss my thematic collections of people :/
I miss pas mal de gens et de choses ici...
Same here. Might be the end of a story.
Groups are not really working yet (though the functionality exists partially, in clients that support it).
You could use your person lists to post about specific topics to specific people, if you wish.
This user guide about Pump.io and this note about changes in Identi.ca might help ;)
