/* Features:
|

* - "latest" mode - display last post number, etc, so that it can be polled by a script.
|
||||
* - force posting with logged-in moderator/janitor name.
|
||||
* - never expire posts.
|
||||
* - allow no-file posts.
|
||||
* - emit PHP instead of html in order to do admin-validation checking.
|
||||
* - give everyone a capcode, and give janitors a tooltip saying which board they're in charge of.

# Parameters:
|

# com: user supplied comment field (before or after wordfilters? dunno)

# md5: md5 of the supplied image. null if no image.
|
||||
# ip: the IP of the user, in integer (packed) form
|
||||
#
|
||||
# Return value: A string. If the string is "OK", the post should go through.

# If the string is anything else, abort posting and display that message

# to the user.

# Integration info;

# This should run before wordfilters (including >>num) and duplicate(md5) detection.

# It doesn't know about bans, so those need to be done seperately, but it
|

# doesn't care if that is before or after.
|

# It really should run after valid file checks (jpg/png/gif, >0x0, etc) but that's not critical.

# Synchronization: There is (in theory) a minor race condition because the tables are not locked.
