How do I find a users log on this site

The easiest way is to add his username to your 'blog friend' list in your log control panel.  See part 12:

Or go to Statistics>User Listing at http://www.beginnertriathlete.com/discussion/statistics/user-listing.asp

It's convenience vs. security really. The issue of security vs. other people having access to blogs has come up a number of times in different ways over the last few months.

Some changes were made to open it up a bit and give you finer control over who can view your training blog. Currently, you can make your training blog completely private so no one can see it, or accessable to BT users only, or make it available to anyone, wether a BT member or not.  

A search by username function would definitely be useful, but I imagine that the easier it is to look up someone else, the more some people would feel uneasy about sharing their log.

Perhaps we could implement this feature, but temper it with 2 enhancements:
1 - the ability to 'opt out' of searches (you're unlisted in the BT phonebook)
2 - add a sub-level of security: your traing blog is accessable to BT users only, but only those on a white list of allowed users. Kind of like the 'Other Blogs' list. It would be best to keep it seperate from the 'Other blogs' list though because the idea of a white list is that it's private.

Thoughts, anyone? 

I would think the ability to opt out of searches or make a log private wich a lot of folks already do would be enough... That is basically what Yahoo does.

As for privacy, this could be just me, but I dont put anything in my log that I would consider private or worth concealing... Actusally if it's in ther it's probably because I want someone to read it.

Any other thoughts?
