Hi @robint,
I’m assuming you mean that you want each of the usernames to be a link to that user’s profile page?
There isn’t currently an option for this. One reason is that the user’s profile page link will be different on different sites. For example, some might want it to hook to the default “author” page provided by WordPress. Other people might be using BuddyPress, and have different URLs for the user profiles.
However, I’ll consider adding this feature in the next version, though it’s possible that it will be too site-dependent. I’ll have to investigate the functions that WordPress provides for getting the user’s URL. Maybe it will really be simple.
In the mean time, if you are comfortable writing some code, you could create a custom module/plugin that hooks into the wordpoints_points_top_users_username
filter, and wraps the username in a link.
