Hallo! I do not see something that is important. Either this is not there or I have done something wrong! It should be possible to have any subscription for a service as unique. If an user has subscribed for a service I do not see any reason why the admin not have the possibility to make it one_time or unique subscription. Lets say that a user subscribes for a Joomla free subscription. Then the details would be inserted to the Joomla database like login, email + password. Hence why should the same subscription appear on the members page? The user has been subscribed already and he should not have a second chance. At the sametime, it should be possible to have multiple subscription for Joomla, like having different areas for different prices or even all for free. Here I see that the UNIQUE or ONETIME possibility of a subscription has been somehow forgotten or missed.
Easy - just look around! Everything you need to do is easy with aMember. Just have a look around the aMember CP (control panel). To stop people signing up to your free subscription more than once, do the following: Go to: aMember CP -> Manage Products -> Click 'Edit' next to your free subscription -> Find the 'Require another subscription to order this product' option and select the options you need Hope this helps! Next time take the effort to actually look around the control panel. You can assign different levels of Joomla access to different subscriptions. Again, you need to look in the Manage Products section to adjust the settings.
Hallo! It has'nt been so long that I bought the product. Hence it takes a while to understand. Manytimes it is easier to read two lines from someone and save days. Thanks for your explaination.
