I have finished the first forum integration for the store plugin.
You can find the plugin in my github repo
If you have mybb, you should know how to install a plugin in mybb.
This plugin works only if you have created a steamid field and your users have filled this field out.
Dont forget to adjust the settings according to your setup.
Please post only the forum you would like to use, if you want to have a forum integration that is not on the vote.
Free and OpenSource forum systems will be preferred, because I donīt own one of the paid systems.
