Oops...batch edit mistake. D'oh!!!
Using Jamroom
Yes, I'm having various complaints about how Groups are functioning, and i realize that not all things can or should be made to work just like they did on Ning. but many things were more logical in Groups on ning, and I know you JR Team created a 'groups' function just for us...for which I am grateful.
"In a Ning group, when anyone posts a message in the group forum, all members of the group are notified about the new message, through email. They don't have to actively log in to monitor the group activity. Unless they turn off that particular messaging option in their privacy settings."
-This is something my members are vocal about missing. They liked being able to 'follow' a whole group to receive notification whenever someone posted a new post in the entire group forum, or when someone created a new group forum discussion. Now they have to specifically 'follow' individual group discussions, and they can totally miss the fact that there are new discussions going on in the group.
As opposed to PJ, I really do need to keep my groups having Comment Walls- otherwise members create superficial 'discussions' for every little silly comment they might have. These comment walls are often used for Group 'idle chitchat', so they get hugely long and i really need to be able to 'clear' them once in a while.
I have another support thread open here right now to try and re-order my Groups' 'forum discussions' so that recent comments will bring a group discussion up to top again...this has been another related problem in groups, and I'm tryng to get a fix for that right now.
Another issue is that because the discussions in Groups are not 'really' discussions, as Gary pointed out...but are rather a post with subsequent 'comments'... this means nobody has the ability to QUOTE from a previous response in order to respond appropriately to some particular point without having to 'explain' what point they are responding to. This is also something members are complaining about every week.
I have no tnymce text editor Quote --or-- COPY/PASTE right-click function, and the 'discussion' replies are really comments so they do not have a 'quote' button either. People are raging that we see copy/past options in the tnymce right clicks, but then get told over and over that we cannot USE the options and must instead use keyboard copy/paste if we want to 'quote' anything. Plus even after we've keyboard copy/pasted a passage from the previous comment... then we can only indent, not really create quotes saying who wrote it.
I do keep explaining over and over to members WHY we can't do these various things, but they really are understandably annoyed and frustrated. Thus, I'm trying to tackle one of these little Group problems at a time here in the JR support forums. THIS thread is about my being able to CLEAR the comment walls occasionally. My other current thread is about ordering the groups' discussions to reflect most recent activity...because members cannot 'follow' a whole Group and are thus missing out on new discussions entirely and are no longer notified on older discussions from ning that they 'used to' get notified about. I will be opening new threads later about the Quote and Copy/Paste issues in Group discussions and comments.
Ok, hope that makes a few things more clear as to where I'm going with all this.
Paul, will wait to see if you are able to somehow get us the ability to more efficiently clear out a group's comment wall without altering anything else in the group... thanks for looking into it!
P.S. still trying to figure out the actual PURPOSE of the Batch Edit page I was in when I accidentally deleted that entire 6 year old group...in my my screenshot. What would one do in that "group comment count" batch edit page ...if not delete group comments?? Easy enough to just delete a whole group from the Group page itself...I figured the 'delete' checkboxes in the page i was on was SURELY for deleting the comments listed to the left of each of the delete boxes...like, HUH??
I'll get back to you here. Meanwhile, thanks for fixing up 2) !
