Hi!Indexing is something that may fasten up a search in a database, more info about should you be able to find here: http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.htmlNote that there's a difference between index and indexing. Index is a way to sepperate different posts...NULL is a "non existing value". An empty value could be NULL (depending on the internal strutur of the programming language).In MySQL you can set a field as NULL or NOT NULL, which means that that field may be empty (NULL), or it isn't allowed to be empty (NOTNULL).Hope that helped some!Good Luck and Don't Panic!
