Thank you for reposting this - I have stoped posting on any group in case they do not find it the right material for them . Now I only post to my group and my friends. If they want to - they can re-post it as you have done.
Thanks for being a friend.
I think you should continue posting them under the groups. Not nessessarily I always get a chance to save them under relevant groups. So, it might get less visibility. Thanks for finding and posting them
