Hi, do you want your members to be not able to delete their posts? If so, what's your use case? Let us understand you better. Thanks!
It is an official forum for our hospital where members of different committees and councils (in different working units) will share their projects and ideas in an interactive way. Once post is made by any member, other members can see and make comments about the applicability and/or challenges in their units. This is part of a hospital accreditation requirements which we plan to implement using this forum. We do not need staff to delete their posts because this will affect sharing the knowledge and experience. Moreover, all the comments under the same post (which are very important ideas from the other members/units) will be deleted. Need your help please.
