Hi fasenderos,
sorry effectively I didn't see that the last manual was not finished, so not public.
You said "what if i need to create my custom db table?"
When you create a content type in SEBLOD, if you add new fields (not existing in article) a new table is created with name of your content type.
For example, if you have a content type named "Blog", SEBLOD will automatically create a table named "#__cck_store_form_blog".
The "Free" storage is pratically never used, except for some specific case (webservice, alias of field in search,...).
The good way => The storage "STANDARD" must be use in 99% of case, and let SEBLOD create table for you.
Best regards.
Lionel
