What do all the numbers in the filename mean ?
That they are using some kind of Content Management System (CMS). The last number identifies the individual entry. Don't know what the 0,1518 means, as it seems to be there in every entry. May be they have different numbers to identify if they are ready to be published or need further editing.
Gruss,
