Effective with Web Crossing version 2.0.2, any post by a guest uses "Guest User" for the second line. Some sysops don't like the change and wish to revert to the earlier behavior.
Answer:
This requires a change to the messageListItem macro.
In messageListItem, change the line:
Example:
%% if authorLine2 %%
%% authorLine2 %%
%% endif %%
to
%% if authorLine2 && authorLine2 != "Guest User" %%
%% authorLine2 %%
%% endif %%
