This blog uses Serendipity.
And it has more than everything I need.
Today I found out one interesting thing.
Here is the story:
when you enter a comment to my entry, you have to enter one code (automatically generated by script in order to prevent spam). If you enter a wrong one, the comment will not be posted. However, your comment is saved in special table in the db. Today I browsed that table and found two comments I did not know I have. So I posted them again, just as like they were posted by their posters. Nice π
