check out default module text/HTML, AFAIK it is the simpliest module allowing to specify, who is able to view or edit the content.

For anyone else interested in doing something similar, here is how I got around this problem:

1. Make module editable by registered users - this effectivly lets all users edit all other users posts
2. Comment out line in 'ModuleActions' property that starts with Actions.Add - this will stop the edit link from showing up even if the user does have edit permission.
3. Create your own link using the EditUrl() function to link to the edit page. Because you have created this one yourself, you can control when it shows up. Here you can check if the userId is the same as who originally posted the listing. If so, display the link.

This is basically all you need to do to get the functionality there. However, it isn't secure because anyone logged in can manually type in a url to edit someone else's post, because technically they have permission to do so, we are just hiding the link. To solve this, make sure in the edit page the first thing you do is once again check that the current userId matches the userId of what they are trying to edit. If not, I just response.redirect them to the homepage.

Well that's what I did and it seems to be working, if anyone sees any flaws in my method please let me know. Thanks!
