Hi @nyilmaz,

Thanks for the feedback.

account sign up.

This one would be hard to pull off correctly since we have a bunch of anti-spam mechanisms built in to our signup flow. It's not impossible but would need some thought to do right.

ability to upgrade guest account to regular one.

Yes, this has been planned for a while. This one will be happening.

more privilage to guest account

What are some examples of what you're looking for?

tMDB users & contributions data

Something for me to think about.

forums data

Maybe. The problem with anything on an API is that it's so easy to abuse. The anti-spam and abuse tools would have to be very well designed.

ability to "append to response" on paged data

No plans for this one I'm afraid.

And a changelog would be great too so we can see changes

For anything of consequence, I'll usually post it on the blog. That's the best place to keep an eye on.
