K2 for Joomla! 1.5 offers many opportunities, but still found that there are other extensions that help you to use it. Let’s look at some of them.
Admin Menu K2
This is new module who offers a full Joomla backend admin menu module with support for K2 Content/Articles. This small extensions basically removes the default backend menu which would normally allow you to select Joomla content such as articles, categories, sections etc. So if your client is using only K2 for content creation, then this will prevent then from accidentally creating Joomla content instead of K2. But remeber to: change it’s position to menu and unpublish Admin menu module (mod_menu) and Admin Quick Icons (mod_quickicon), for Joomla Content.

K2 Store
This a simple & free shopping cart extension for k2. It has Paypal/authorize.net Payment plugins and Attachment Downloads on order completion.
K2 User Plugin
It assigns the users automatically to a K2 group. If you use other extension for users handling (like JomSocial, VirtueMart and similar), the users do not have any K2 user group assigned. And then this small modification solves that issue. The user is automatically assigned to the registered users group in K2 (or other if you set it in the plugin parameters). This plugin does the trick for newly registered users only.
