Currently I am a memeber of the OpenACS Core Team that helps to guide and improve the toolkit.
Right now I am maintaing the Content Repository, File-Storage, and WebDAV support packages.
I recently added a tsearch2-driver implementation for PostgreSQL based full text search within OpenACS. It is based on tsearch2 for PostgreSQL 7.3 and up. In addition I am working on adding extended search capabilities to combine full text index search with regular SQL queries.
