Fieldtype "UserArray" possible?

[tsdtsdtsd]

Hi,

I'm in need of a Fieldtype which I couldn't find in the modules database and as I'm new to module development I wanted to ask for your opinions.

What i need is a Filedtype like "Page" (the PageArray multiselect to be precise), but instead of choosing pages from the tree I need to be able to choose multiple users, which for example I will iterate over later on and compare with the current $user. 

My question is - before I dive into module development and have a hard time figuring it out - is my fieldtype even possible? 

As far as I can think of, I would need to retrieve a list of users from the database directly and work with it.

Also, if you have any awesome hints for a mod-dev-noob (like links to good articles, except ryans guide) it would be appreciated   but that's not that important as there are lots of modules I can learn from anyway.

Thanks, and have a good night

Users actually are pages in tree, so you already have what you need with page field and it's various inputfields.

Just to clarify:

When defining the "Selectable Pages" in the PageField's input tab, select the users from the page tree: Admin > Access > Users

Hadn't thought about that -.-

Sorry for the inconvenience caused... and thank you guys

tsd,

Also wanted to mention that module development isn't that difficult. Start here.
