Posting "in" and then jamming out is exactly the same as "flaking" on a deal to purchase something.
"tentative" means nothing and should NEVER be posted ..
"IN" means you will be there, you have the money , you have a ride, and you are committed to attend.
true BUT, tentative is useful IMO to say, I have something to check before I confirm my presence (example: having your day off the job, your gun is at a gun doc and it should be ready but you are not sure. etc.)
I shows the host that if everything is alright then you will attend.
If you say IN, you are 110% sure you will attend unless a nuclear war begins (ie, you're gun doesent work or your kid is diying)
