Change Project Amount Near End?

Haven’t spoken to you for a while.  Hope you’re doing alright.

Question:  Is it OK for project owners to change the project amount

once their project has been approved and is published?

As it stands right now, the project owner can basically set up any amount

they wish when creating their project and half way through the project or

when the project nears the end, the project owner can simply edit the project

and lower the requested amount to match the total amount pledged and thus

collect money (good for us, coz we get paid as well).  

But is that correct?

Shouldn’t it be that once the project request amount has been set and

the project is ‘live’, the amount can not be changed for the duration of

the project?

Let me know when you have a chance please.

Thanks
