PM on greenfoot.org

There should be a forum as well (I mean I proper forum, not the one now which gives you the option to talk about programming and other) But I support this completely.

@erdelf: The user-to-user communication sounds like a useful feature, but it's not top of our priority list right now. The notion of being "online" on a web forum is always a bit hacky (it usually comes down to: did they load a page in the last 5 mins) so I'm not so keen on that. @Denzien: Which features of forums were you looking for? I'd quite like an interface like Stack Overflow, but we're too busy making Greenfoot to also make a decent clone of Stack Overflow!

Any replies?

Adding function requires site development, not just administration. Teaching a user all the necessary details and then checking any code that they wrote (necessary to make sure no security holes are introduced etc) would take more time from us than would adding the feature ourselves. Also, we have to be really sure we want it first. The focus of the site is really about public collaboration.

Well, I saw the wish of a PM-function in a discussion started a year ago. I just thought when it isn't implemented after a year, you could need help. I made a new post there a few minutes ago, so you should be able to find it easily.

There's a number of questions that arise over this, and only one of them is the technical difficulty! If we really wanted to do this and it was at the top of our priority list we could do, but I'm actually far from convinced it's something that would be beneficial to implement at all. For reasons as to why, take a look at the similar question that was asked here on StackOverflow. Specifically: It's far from a clear cut issue, and I'm not saying it's something that will definitely never be implemented - but don't hold your breath!

to the second: Well, I think I can choose what I read and what not. to the first: I think I can decide whom I give my informations. If I want to share it with everyone on this site, I would do that. But when I ask for the code of something and he wants to give it only to me, because he likes my work or whatever?

I choose not to read spam that gets delivered to my email address - it doesn't mean I like it being there :-) The other way to look at it is while you may simply ignore such messages, that doesn't necessarily mean that everyone will! If you really want to do that sort of thing, then there's ways around it, such as putting an email address you can be contacted on in your "about" section (which I notice that you've done.) But there's a difference between technically making it possible, and providing a bespoke feature which encourages its use - and may well lead to questions being asked via PM that could have been asked in a forum post and benefited everyone.
