realname causes problems with other modules

I found that when you override the username with the realname, this can cause a problem in some modules, such as Blog Add Ons, because two different people can have the same realname with a different case, which will cause two user's blogs to be mixed together. This problem is caused by the fact that user_load uses LOWER to make all the names the same case. So, for example, if one user's realname is krissy, and another is Krissy, their blogs will be merged. You can solve this problem by changing the following line (170 in realname.module):

      $stuff['%'. $i] = check_plain($account->$name);

to

      $stuff['%'. $i] = strtolower(check_plain($account->$name));
