The restriction on backdating is irrelevant -- the "problem" is the way 
journals and communities sort entries.  In particular, even if 
backdating were possible in communities, the entry still wouldn't stay 
at the top of the page.

Without getting too technical: Personal journals sort entries by the 
date given in the entry.  The theory is that most of the time, you're 
going to write in chronological order.  So a future-dated entry will 
always show up at the top, because that's the most recent according to 
entry dates.  The backdate option evolved, for various reasons that I 
won't get into, as a "yes I know this entry is being posted out of 
order" flag, because otherwise LJ complains that you're posting out of 
order.

Community journals, OTOH, sort entries by the server date/time when they 
were posted.  This happens because multiple people are going to be 
posting to communities, and they may be living in different time zones. 
  If someone posts at 2:30pm EST, and five minutes later someone posts 
at 11:35pm PST, the second post is going to appear above the first one 
because, even though it has an earlier time, it was posted later.  (The 
same logic is used for friends pages, ftr: in both cases, you don't want 
to miss seeing an entry just because it has an earlier timestamp.) 
Because there isn't the same restriction on chronological order, you 
don't need to flag any entries with "backdate" -- but also, 
future-dating a post doesn't keep it at the top.

So it isn't *quite* as simple as "remove the 'no backdate in comms' line 
of code".  *wry grin*  If there is some sort of "this post is sticky" 
flag, which I'd assume could be used in personal journals (getting 
around the future-dating thing) as well as communities, that would work; 
but backdating a community entry wouldn't do anything for keeping it at 
the top.
