Salutes are used to show your appreciation for a post by a user. More salutes tends to mean more people agree with that person, or they're friendly.
In my case I just post a lot.
If you wanted developer feedback on your workshop item, or to ask exactly how the workshop process works, don't be scared to email feedback@musegames.com
They're very good with speedy and friendly replies, and if they feel anything needs to be changed they'll give constructive feedback too.
Although the devs do browse the forums, most replies will be from community members
