Zoho Permissions - Edit and Delete permissions

Zoho Permissions - Edit and Delete permissions

Hey there guys,

I've been working on locking down the permissions a little bit in Zoho and am having trouble figuring out how this is done.

I want users to be able to edit and delete their own comments but not be able to delete other people's comments.

I've already heard an instance where someone deleted a comment posted by someone else to eliminate evidence.  I'd hate to have that happen again.

Any tips or ideas or is this not possible.

Thanks so much,
