Hi, yes I have red that page. And also I look the junior jobs. It mention that bug fixing and I have look at the bug list in sourceforge. There are lot of bugs. So if you can, please let me know if there are any bugs which is related to tbl_change.php, tbl_replace.php, libraries/tbl_replace_fields.inc.php. So it will help me to understand and familiar with those php files. Because that project idea mention those php file to refactoring.
