Membership gives you access to the paid extensions and apps and to support for those extensions, there is no general Seblod support included except if you have Premium membership that also includes 1 hour of support. If you have question regarding your purchased extensions or apps, there are special forums for each of them and you should ask your question there.
If you have general Seblod questions, community forum is the right place for such questions, alternatively you can purchase dedicated support hours (under Sotre-Services)
