At the top of each individual reply, there are a series of icons - one of which looks like . If you click on the icon you will be taken to the general public's view of that person's profile (so if you click on the icon in the section containing my reply to your post, you will be taken to a page showing the things that you are allowed to see of my profile. From that page, there is a link to "show recent posts" - so you can look at all the recent posts for that user.
Alternatively (depending on whether the previous suggestion meets your needs or not), there is also an option on the search page to search a particular forum by member number - the member number is listed just below the user's name. For example, your member number is 111515 and my member number is 47425.
Does that help?

I assume you are talking about the first search capability?
I am not sure how you would see this working within the search screen itself. There are over 138,000 registered users on JavaRanch, so providing a pull-down list is not really an option :-)
Looking at it from a different perspective, having some way to search by user name might be more workable. But this could be difficult to achieve, especially when you have a common name (such as "John Smith"), which may have alternate spellings ("Jon", "Jonathon", "Johannes", "Smyth", "Smythe", "Smitty"...). So there would have to be a lot of hard work done by some volunteers to try and add such functionality into the software.
