HI,
i dont know if it is possible, but an rss feed feature would be great. With this the people could see it on feed, without having in there.
The option to see users in chat would the great, because the people havent to go in and look for it. So you can see if there are people on from Desktop.
The other option, to see the messages typed in is not such important, because when i want to see this i can go on, but i want to write this too, for later.
