If like me you want to find a thread and you know who started it but cant quite remember what the magic search words were ; this feature is for you
Find the persons name ( it happens so its me and I am online )
Click the portfolio button
This then displays all the posts that the person has started
You might not see the person online but you can find them by going into the users section. If thats not visible click | more
You can then have a look see or filter by name
That will then display the user , click the user and select portfolio
This will then show all the posts by that person
