As far as I know, you cannot show ALL of your posts, full-text, in one continuous list. If there's some way to do it (a well hidden method
) I haven't come across it.
I see you have been here for a few years, so you likely know what I am about to write, but for the benefit of newer members:
To see all of your post TITLES, or all of the THREADS where you have posts, use the LQ Search page, and enter your username in the area for "Find posts by This User" near the right side, and on the left side, select either "show as posts" or "show as threads" (this is similar to what XavierP has just written).
I hope this is accurate and helps you.
Cheers,
Sasha
