I've been doing a bit of beta testing just recently - for various people and have found out something which might be of use to everyone. The IDs of conversation do actually matter to some extent.
When conversing with people there doesn't seem to be a problem what number you use, but when using conversations with say a book, grave, or other inanimate object you can't use number under 100 because most of the time they will not work.
