If you want to remove the usersname, as well as the clicking, it the template header find and remove the following.

<li class="welcomelink">{vb:rawphrase welcome_x_link_y, {vb:raw bbuserinfo.username}, {vb:link member, {vb:raw bbuserinfo}}}</li>

If you want to remove just the ability to click on it edit the phrase welcome_x_link_y and change it to this.

Welcome, {1}
