I have the following sharepoint workflow work :
1. Create a sharepoint list where the form should generate an automatic Application number with other optional and mandatory fields and the workflow starts.
2. Documents uploaded from this form should goto one specific document library with a document name automatically generated.
3. In another form of a step in workflow the documents for the application number may be opened by users if they wish.
4. Sharepoint branding, updating the sharepoint website page styles, layout and color.
Please ask me if you have further questions. Would like if somebody can show me these steps.
