although I wrote "bump" everytime I was also adding something to the discussion.
If you want to add a new information to a thread, it doesn't have to include the word 'bump', you could use update, alert or any other phrase to indicate it's an important information. Not every new reply should be a bump, this way you do not have to delete your previous replies when making a new one. This is one of the reasons users reserve a few replies after the OP to add new information.
Also, bumps are limited to every 24 hours, but you do not have to cut it clean, ideally only bump when necessary, or it could seem like you're trying to force engagements.
