There's no way to determine whether any of the participants are even alive, let alone monitoring something from that long ago.
Do you keep track of what you typed on your computer on some stormy Thursday, six years ago?
Just post your question to whichever forum space is most appropriate to whatever your current topic might be and hope for someone to respond with current knowledge.

Try reading this thread (that was 4th on the front list when you posted) for storing PDF in a table....
Mike - yes, Yes, YES!!!!!
2 and a half days of going nuts over this and I was able to get the pdf I'm creating stored as a blob in my test db in a half hour by following Storing and Accessing Reports in the Database link from the other post.
I wasn't considering my PDF a 'report' because it's not like a report that would be shown in a region (it's basically a Word signature form with just one or two values from the app needed), so I think that I wasn't searching for the answer with the appropriate terminology. In other words, I'm a noob and don't understand APEX very well (yet). Regardless - I'm cooking, now.
