I do like such features as follow...
- Access Control for each snip: Yes, some logs just a private log, not public.
- CATPCHA support
- Integration of Digg It / Del.icio.us feature: but also Yahoo/Google bookmarks or others.
- A completely emoticon / smileys system: add a new smiley/emoticon is not easy ( write the new code, compile , copy jar file, restart jsp container ). Some of blog site use javascript to implement this feature, it seems a easy way but I am tring to understand how it does.

Some thing about the forked version:
* maybe use maven 2 to manage the project status, ThoMo had a {link:Radeox maven2 project|http://snipsnap.org/comments/ThoMo/Radeox}.
* I suggest to use a newest version of lucene library because v1.2 can not fully support CJK. Currently I used 1.9.1 for it.
* hmm... the name of the fork version is really a question...

Just fixed some words.... :p
